commit 8d28b7a7 upstream. Drivers may need to provide their own get_cd() mmc host op, but currently the internals of the current op (sdhci_get_cd()) are provided by sdhci_do_get_cd() which is also called from sdhci_request(). To allow override of the get_cd functionality, change sdhci_request() to call ->get_cd() instead of sdhci_do_get_cd(). Note, in the future the call to ->get_cd() will likely be removed from sdhci_request() since most drivers don't need actually it. However this change is being done now to facilitate a subsequent bug fix. Signed-off-by:

commit bf60e592 upstream. In the past, fixes for specific hardware devices were implemented in sdhci using quirks. That approach is no longer accepted because the growing number of quirks was starting to make the code difficult to understand and maintain. One alternative to quirks, is to allow drivers to override the default mmc host operations. This patch makes it easy to do that, and it is needed for a subsequent bug fix, for which separate patches are provided. Signed-off-by:

commit 163cbe31 upstream. Intel BXT/APL use a card detect GPIO however the host controller will not enable bus power unless it's card detect also reflects the presence of a card. Unfortunately those 2 things race which can result in commands not starting, after which the controller does nothing and there is a 10 second wait for the driver's 10-second timer to timeout. That is fixed by having the driver look also at the present state register to determine if the card is present. Consequently, provide a 'get_cd' mmc host operation for BXT/APL that does that.

commit 41c89159 upstream. The commit fixing the conversion of pxamci to slot-gpio API fixed the inverted the logic of the read-only gpio. Unfortunately, the commit was tested on a non-inverted gpio, and not on the inverted one. And the fix did work partially, by luck. This is the remaining missing part of the fix, trivial but still necessary. Fixes: Fixes: 26d49fe7 ("mmc: pxamci: fix read-only gpio detection polarity") Reported-by:

commit 0bcb7efd upstream. commit 4956e109 ("ARM: 6244/1: mmci: add variant data and default MCICLOCK support") added variant data for ARM, U300 and Ux500 variants. The Nomadik NHK8815/8820 variant was erroneously labeled as a U300 variant, and when the proper Nomadik variant was later introduced in commit 34fd4213 ("ARM: 7378/1: mmci: add support for the Nomadik MMCI variant") this was not fixes. Let's say this fixes the latter commit as there was no proper Nomadik support until then. Fixes: 34fd4213 ("ARM: 7378/1: mmci: add support for the Nomadik...") Signed-off-by:

commit e10c3219 upstream. While in sdhci_execute_tuning() the choice whether or not to enable the tuning is done on the actual timing, in the mmc_sdio_init_uhs_card() the check is done on the capability of the card. This difference is causing some issues with some SDIO cards in DDR50 mode where the CDM19 is wrongly issued. With this patch we modify the check in both mmc_(sd|sdio)_init_uhs_card() functions to take the proper decision only according to the actual timing specification. Signed-off-by:

commit 5c671c41 upstream. sdhci has a legacy facility to prevent runtime suspend if the bus power is on. This is needed in cases where the power to the card is dependent on the bus power. It is controlled by a pair of functions: sdhci_runtime_pm_bus_on() and sdhci_runtime_pm_bus_off(). These functions use a boolean variable 'bus_on' to ensure changes are always paired. There is an additional check for 'runtime_suspended' which is the problem. In fact, its use is ill-conceived as the only requirement for the logic is that 'on' and 'off' are paired, which is actually broken by the check, for example if the bus power is turned on during runtime resume. So remove the check. Signed-off-by:

commit adb24d42 upstream. Commit cc4f414c ("mmc: mmc: Add driver strength selection") added driver strength selection for eMMC HS200 and HS400 modes. That patch also set the driver stength when transitioning through High Speed mode to HS200/HS400, but driver strength is not defined for High Speed mode. While the JEDEC specification is not clear on this point it has been observed to cause problems for some eMMC, and removing the driver strength setting in this case makes it consistent with the normal use of High Speed mode.

commit d9bfbb95 upstream. The 'ocr' parameter passed to mmc_set_signal_voltage() defines the power-on voltage used when power cycling after a failure to set the voltage. However, in the case of mmc_sdio_init_card(), the value passed has the R4_18V_PRESENT flag set which is not valid for power-on and results in an invalid vdd. Fix by passing the card's ocr value which does not have the flag. Signed-off-by:

commit 347ea32d upstream. SDHCI has built-in DMA called ADMA2. ADMA2 uses a descriptor table to define DMA scatter-gather. Each desciptor can specify a data length up to 65536 bytes, however the length field is only 16-bits so zero means 65536. Consequently, putting zero when the size is zero must not be allowed. This patch fixes one case where zero data length could be set inadvertently. The problem happens because unaligned data gets split and the code did not consider that the remaining aligned portion might be zero length. That case really only happens for SDIO because SD and eMMC cards transfer blocks that are invariably sector- aligned. For SDIO, access to function registers is done by data transfer (CMD53) when the register is bigger than 1 byte. Generally registers are 4 bytes but 2-byte registers are possible. So DMA of 4 bytes or less can happen. When 32-bit DMA is used, the data alignment must be 4, so 4-byte transfers won't casue a problem, but a 2-byte transfer could. However with the introduction of 64-bit DMA, the data alignment for 64-bit DMA was made 8 bytes, so all 4-byte transfers not on 8-byte boundaries get "split" into a 4-byte chunk and a 0-byte chunk, thereby hitting the bug. In fact, a closer look at the SDHCI specs indicates that only the descriptor table requires 8-byte alignment for 64-bit DMA. That will be dealt with in a separate patch, but the potential for a 2-byte access remains, so this fix is needed anyway. Signed-off-by:

commit 1b9f2372 upstream. The posix_clock_poll function is supposed to return a bit mask of POLLxxx values. However, in case the hardware has disappeared (due to hot plugging for example) this code returns -ENODEV in a futile attempt to throw an error at the file descriptor level. The kernel's file_operations interface does not accept such error codes from the poll method. Instead, this function aught to return POLLERR. The value -ENODEV does, in fact, contain the POLLERR bit (and almost all the other POLLxxx bits as well), but only by chance. This patch fixes code to return a proper bit mask. Credit goes to Markus Elfring for pointing out the suspicious signed/unsigned mismatch. Reported-by:

commit 004fa08d upstream. When the GIC is using EOImode==1, the EOI is done immediately, leaving the deactivation to be performed when the EOI was previously done. Unfortunately, the ITS is not aware of the EOImode at all, and blindly EOIs the interrupt again. On most systems, this is ignored (despite being a programming error), but some others do raise a SError exception as there is no priority drop to perform for this interrupt. The fix is to stop trying to be clever, and always call into the underlying GIC to perform the right access, irrespective of the more we're in.

commit 385277bf upstream. When there is an error copying a chunk dm-snapshot can incorrectly hold associated bios indefinitely, resulting in hung IO. The function copy_callback sets pe->error if there was error copying the chunk, and then calls complete_exception. complete_exception calls pending_complete on error, otherwise it calls commit_exception with commit_callback (and commit_callback calls complete_exception). The persistent exception store (dm-snap-persistent.c) assumes that calls to prepare_exception and commit_exception are paired. persistent_prepare_exception increases ps->pending_count and persistent_commit_exception decreases it. If there is a copy error, persistent_prepare_exception is called but persistent_commit_exception is not. This results in the variable ps->pending_count never returning to zero and that causes some pending exceptions (and their associated bios) to be held forever. Fix this by unconditionally calling commit_exception regardless of whether the copy was successful. A new "valid" parameter is added to commit_exception -- when the copy fails this parameter is set to zero so that the chunk that failed to copy (and all following chunks) is not recorded in the snapshot store. Also, remove commit_callback now that it is merely a wrapper around pending_complete. Signed-off-by:

commit 4623e596 upstream. In the 3.17 kernel the poll() behavior changed for output streams: as long as not all buffers were queued up poll() would return that userspace can write. This is fine for the write() call, but when using stream I/O this changed the behavior since the expectation was that it would wait for buffers to become available for dequeuing. This patch only enables the check whether you can queue buffers for file I/O only, and skips it for stream I/O. Signed-off-by:

commit d2cc2f0b upstream. A previous patch added a check if the firmware is too big, but it didn't set the return error code with the right value. [mchehab@osg.samsung.com: I ended by applying a v1 of Laura's patch, without the proper return code. This patch contains the difference between v2 and v1 of the Laura's "si2157: Bounds check firmware" patch] Signed-off-by:

commit c9d57de6 upstream. When in FE_TUNE_MODE_ONESHOT the frontend must report the actual capabilities so user can take appropriate action. With frontends that can't do auto inversion this is done by dvb-core automatically so CAN_INVERSION_AUTO is valid. However, when in FE_TUNE_MODE_ONESHOT this is not true. So only set FE_CAN_INVERSION_AUTO in modes other than FE_TUNE_MODE_ONESHOT Signed-off-by:

commit 768acf46 upstream. The driver allocates the spinlock but fails to initialize it correctly. The kernel reports a BUG indicating bad spinlock magic when spinlock debugging is enabled. Call spin_lock_init() on it to initialize it correctly. Fixes: b4e3e59f ("[media] rc: add sunxi-ir driver") Signed-off-by:

commit d4565649 upstream. both do_last() and walk_component() risk picking a NULL inode out of dentry about to become positive, *then* checking its flags and seeing that it's not negative anymore and using (already stale by then) value they'd fetched earlier. Usually ends up oopsing soon after that... Signed-off-by:

commit 7079604d upstream. This driver has a number of errors in the module initialization. These include the following: Parameter msi_support is stored in two places - one is removed. Paramters sw_crypto and disable_watchdog were never stored in the final locations, nor were they initialized properly. Signed-off-by:

commit 793b0999 upstream. This driver has some errors in the handling of module parameters. These include missing initialization for parameters msi_support and disable_watchdog. In addition, neither of these parameters nor sw_crypto are transferred into the locations used by the driver. A final fix is adding parameter msi to the module named and description macros.

commit f99551a2 upstream. In commit 38506ece (rtlwifi: rtl_pci: Start modification for new drivers), a bug was introduced that causes a NULL pointer dereference. As this bug only affects the infrequently used RTL8192EE and only under low-memory conditions, it has taken a long time for the bug to show up. The bug was reported on the linux-wireless mailing list and also at https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/ as bug #1527603 (kernel crashes due to rtl8192ee driver on ubuntu 15.10).
