commit 82ee3aeb upstream. Samsung has just released a portable USB3 SSD, coming in a very small and nice form factor. It's USB ID is 04e8:8001, which unfortunately is already used by the Palm Visor driver for the Samsung I330 phone cradle. Having pl2303 or visor pick up this device ID results in conflicts with the usb-storage driver, which handles the newly released portable USB3 SSD. To work around this conflict, I've dug up a mailing list post [1] from a long time ago, in which a user posts the full USB descriptor information. The most specific value in this appears to be the interface class, which has value 255 (0xff). Since usb-storage requires an interface class of 0x8, I believe it's correct to disambiguate the two devices by matching on 0xff inside visor.

commit 18cc2f4c upstream. Our event ring consists of only one segment, and we risk filling the event ring in case we get isoc transfers with short intervals such as webcams that fill a TD every microframe (125us) With 64 TRB segment size one usb camera could fill the event ring in 8ms. A setup with several cameras and other devices can fill up the event ring as it is shared between all devices. This has occurred when uvcvideo queues 5 * 32TD URBs which then get cancelled when the video mode changes. The cancelled URBs are returned in the xhci interrupt context and blocks the interrupt handler from handling the new events. A full event ring will block xhci from scheduling traffic and affect all devices conneted to the xhci, will see errors such as Missed Service Intervals for isoc devices, and and Split transaction errors for LS/FS interrupt devices. Increasing the TRB_PER_SEGMENT will also increase the default endpoint ring size, which is welcome as for most isoc transfer we had to dynamically expand the endpoint ring anyway to be able to queue the 5 * 32TDs uvcvideo queues. The default size used to be 64 TRBs per segment Signed-off-by:

commit d104d015 upstream. Isoc TDs usually consist of one TRB, sometimes two. When all goes well we receive only one success event for a TD, and move the dequeue pointer to the next TD. This fails if the TD consists of two TRBs and we get a transfer error on the first TRB, we will then see two events for that TD. Fix this by making sure the event we get is for the last TRB in that TD before moving the dequeue pointer to the next TD. This will resolve some of the uvc and dvb issues with the "ERROR Transfer event TRB DMA ptr not part of current TD" error message Signed-off-by:

commit d65d2b25 upstream. The state of m_td0TD0.f1Owner should change after the buff_addr has been filled otherwise the device grabs the buffer too early. m_td0TD0.f1Owner is protected by memory barriers on both sides of change. iTDUsed is best incremented after MACvTransmit. It appears that f1Owner actually polls to do the memory transfer. A back port patch will be needed for v3.19 Signed-off-by:

After it writing AT commands to /dev/GCT-ATM0 is unsuccessful (no echo, no response) and dmesg show "gdmtty: invalid payload : 1 16 f011". Before that commit value of dummy_cnt was only a padding size. After using ALIGN() this value is increased by its first argument. So the following usage of this variable needs correction.

commit 3530febb upstream. This reverts commit 7290006d. Through the regression report, it was revealed that the tpacpi_led_set() call to thinkpad_acpi helper doesn't only toggle the mute LED but actually mutes the sound. This is contradiction to the expectation, and rather confuses user. According to Henrique, it's not trivial to judge which TP model behaves "LED-only" and which model does whatever more intrusive, as Lenovo's implementations vary model by model. So, from the safety reason, we should revert the patch for now. Reported-by:

commit d2a5d46b upstream. Before commit 035a61c3 ("clk: Make clk API return per-user struct clk instances") we acquired the enable_lock in __clk_set_parent_{before,after}() by means of calling clk_enable(). After commit 035a61c3 we use clk_core_enable() in place of the clk_enable(), and clk_core_enable() doesn't acquire the enable_lock. This opens up a race condition between clk_set_parent() and clk_enable(). Fix it.

commit 97372e5a upstream. Commit ae43b328 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power Management support v12") added pm support for the pl330 dma driver but it makes the clock for the Exynos5420 MDMA0 DMA controller to be gated during suspend and this in turn makes its parent clock aclk266_g2d to be gated. But the clock needs to be ungated prior suspend to allow the system to be suspend and resumed correctly. Add GATE_BUS_TOP register to the list of registers to be restored when the system enters into a suspend state so aclk266_g2d will be ungated. Thanks to Abhilash Kesavan for figuring out that this was the issue. Fixes: ae43b328 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power Management support v12") Signed-off-by:
