commit 6c5c04e5 upstream. The purpose of this patch is to remove a section of "bad" code that assigns the last DAC to ports E or F in order to support notebooks with docking in earlier days, around ALSA 1.0.19 - 21. This is not necessary now and actually breaks some configurations that use these ports as other devices. This have been tested on several different configurations to make sure that it is working for different combinations. Signed-off-by:

commit 54b5e3a4 upstream. Kill the local smp response buffer. Besides being unnecessary, it is too small (currently truncates responses to 60 bytes). The mid-layer will have already allocated a sufficiently sized buffer, just kmap and copy into it directly. Reported-by:

commit 5d7c20b7 upstream. During kdump testing I noticed timeouts when initialising each IPR adapter. While the driver has logic to detect an adapter in an indeterminate state, it wasn't triggering and each adapter went through a 5 minute timeout before finally going operational. Some analysis showed the needs_hard_reset flag wasn't getting set. We can check the reset_devices kernel parameter which is set by kdump and force a full reset. This fixes the problem. Signed-off-by:

commit f575c5d3 upstream. The following patch for megaraid_sas will fix a potential bad pointer access in megasas_reset_timer(), when a MegaRAID 9265/9285 or 9360/9380 gets a timeout. megasas_build_io_fusion() sets SCp.ptr to be a struct megasas_cmd_fusion *, but then megasas_reset_timer() was casting SCp.ptr to be a struct megasas_cmd *, then trying to access cmd->instance, which is invalid. Just loading instance from scmd->device->host->hostdata in megasas_reset_timer() fixes the issue. Signed-off-by:

commit 3e309cdf upstream. Commit 15bed0f2 added a quirk for the e823 Ricoh card reader to lower the base frequency. However, the quirk first checks to see if the proprietary MMC controller is disabled, and returns if so. On some devices, such as the Lenovo X220, the MMC controller is already disabled by firmware it seems, but the frequency change is still needed so sdhci-pci can talk to the cards. Since the MMC controller is disabled, the frequency fixup was never being run on these machines. This moves the e823 check above the MMC controller check so that it always gets run.

commit 7f7e4129 upstream. During a rescan operation mmc_attach(sd|mmc|sdio) functions are called. The error handling in these function can trigger a detach of the bus, which also meant a power off. This is not notified by the rescan operation which then continues to the next attach function. If a power off has been done, the framework must never send any new commands to the host driver, without first doing a new power up. This will most likely trigger any host driver to hang. Moving power off out of detach and instead handle power off separately when it is actually needed, solves the issue. Signed-off-by:

commit d0d0a225 upstream. When force == false, we don't do load detection in the connector detect functions. Unforunately, we also return the previous connector state so we never get disconnect events for DVI-I, DVI-A, or VGA. Save whether we detected the monitor via load detection previously and use that to determine whether we return the previous state or not.

commit f52c619a upstream. The commit 47356eb6 introduced a mechanism to record the backlight level only at disabling time, but it also introduced a regression. Since intel_lvds_enable() may be called without disabling (e.g. intel_lvds_commit() calls it unconditionally), the backlight gets back to the last recorded value. For example, this happens when you dim the backlight, close the lid and open the lid, then the backlight suddenly goes to the brightest. This patch fixes the bug by recording the backlight level always when changed via intel_panel_set_backlight(). And, intel_panel_{enable|disable}_backlight() call the internal function not to update the recorded level wrongly. Signed-off-by:

commit 7e393a83 upstream. Setting the chain (CH) bit in the link TRB of isochronous transfer rings is required by AMD 0.96 xHCI host controller to successfully transverse multi-TRB TD that span through different memory segments. When a Missed Service Error event occurs, if the chain bit is not set in the link TRB and the host skips TDs which just across a link TRB, the host may falsely recognize the link TRB as a normal TRB. You can see this may cause big trouble - the host does not jump to the right address which is pointed by the link TRB, but continue fetching the memory which is after the link TRB address, which may not even belong to the host, and the result cannot be predicted. This causes some big problems. Without the former patch I sent: "xHCI: prevent infinite loop when processing MSE event", the system may hang. With that patch applied, system does not hang, but the host still access wrong memory address and isoc transfer will fail. With this patch, isochronous transfer works as expected. This patch should be applied to kernels as old as 2.6.36, which was when the first isochronous support was added for the xHCI host controller. Signed-off-by:

commit 0e6c7f74 upstream. There are 2 situations wherein the xhci_ring* might not get freed: - When xhci_ring_alloc() -> xhci_segment_alloc() returns NULL and we goto the fail: label in xhci_ring_alloc. In this case, the ring will not get kfreed. - When the num_segs argument to xhci_ring_alloc is passed as 0 and we try to free the rung after that. ( This doesn't really happen as of now in the code but we seem to be entertaining num_segs=0 in xhci_ring_alloc ) This should be backported to kernels as old as 2.6.31. Signed-off-by:

Alan Stern authored
commit 68aa95d5 upstream. This patch (as1489) works around a hardware bug in MosChip EHCI controllers. Evidently when one of these controllers increments the frame-index register, it changes the three low-order bits (the microframe counter) before changing the higher order bits (the frame counter). If the register is read at just the wrong time, the value obtained is too low by 8. When the appropriate quirk flag is set, we work around this problem by reading the frame-index register a second time if the first value's three low-order bits are all 0. This gives the hardware a chance to finish updating the register, yielding the correct value. Signed-off-by:

commit e8df1674 upstream. If the usermode app does an ioctl over this serial device by using TIOCMIWAIT, then the code will wait by setting the current task state to TASK_INTERRUPTIBLE and then calling schedule(). This will be woken up by the qt2_process_modem_status on URB completion when the port_extra->shadowMSR is set to the new modem status. However, this could result in a lost wakeup scenario due to a race in the logic in the qt2_ioctl(TIOCMIWAIT) loop and the URB completion for new modem status in qt2_process_modem_status. Due to this, the usermode app's task will continue to sleep despite a change in the modem status. Signed-off-by:

commit c5a48592 upstream. A return value of -EINPROGRESS from pm_runtime_get indicates that the device is already resuming due to a previous call. Internally, usb_autopm_get_interface_async doesn't treat this as an error and increments the usage count, but passes the error status along to the caller. The logical assumption of the caller is that any negative return value reflects the device not resuming and the pm_usage_cnt not being incremented. Since the usage count is being incremented and the device is resuming, return success (0) instead. Signed-off-by:

commit fa90e1c9 upstream. If tty_add_file fails at the point it is now, we have to revert all the changes we did to the tty. It means either decrease all refcounts if this was a tty reopen or delete the tty if it was newly allocated. There was a try to fix this in v3.0-rc2 using tty_release in 0259894c (TTY: fix fail path in tty_open). But instead it introduced a NULL dereference. It's because tty_release dereferences filp->private_data, but that one is set even in our tty_add_file. And when tty_add_file fails, it's still NULL/garbage. Hence tty_release cannot be called there. To circumvent the original leak (and the current NULL deref) we split tty_add_file into two functions, making the latter non-failing. In that case we may do the former early in open, where handling failures is easy. The latter stays as it is now. So there is no change in functionality. The original bug (leak) was introduced by f573bd17 (tty: Remove __GFP_NOFAIL from tty_add_file()). Thanks Dan for reporting this. Later, we may split tty_release into more functions and call only some of them in this fail path instead. (If at all possible.) Introduced-in: v2.6.37-rc2 Signed-off-by:
