[Linux-stable-mirror] [PATCH 1/2] xhci: Don't show incorrect WARN message about events for empty rings

by Mathias Nyman

xHC can generate two events for a short transfer if the short TRB and last TRB in the TD are not the same TRB. The driver will handle the TD after the first short event, and remove it from its internal list. Driver then incorrectly prints a warning for the second event: "WARN Event TRB for slot x ep y with no TDs queued" Fix this by not printing a warning if we get a event on a empty list if the previous event was a short event.

[Linux-stable-mirror] [PATCH] mmc: sdhci: Avoid swiotlb buffer being full

by Ulf Hansson

The commit de3ee99b097d ("mmc: Delete bounce buffer handling") deletes the bounce buffer handling, but also causes the max_req_size for sdhci to be increased, in case when max_segs == 1. This causes errors for sdhci-pci Ricoh variant, about the swiotlb buffer to become full. Fix the issue, by taking IO_TLB_SEGSIZE and IO_TLB_SHIFT into account when deciding the max_req_size for sdhci.

[Linux-stable-mirror] [PATCH] Bluetooth: btsdio: Do not bind to non-removable BCM43341

by Hans de Goede

BCM43341 devices soldered onto the PCB (non-removable) always (AFAICT) use an UART connection for bluetooth. But they also advertise btsdio support on their 3th sdio function, this causes 2 problems: 1) A non functioning BT HCI getting registered 2) Since the btsdio driver does not have suspend/resume callbacks, mmc_sdio_pre_suspend will return -ENOSYS, causing mmc_pm_notify() to react as if the SDIO-card is removed and since the slot is marked as non-removable it will never get detected as inserted again. Which results in wifi no longer working after a suspend/resume. This commit fixes both by making btsdio ignore BCM43341 devices when connected to a slot which is marked non-removable.

[Linux-stable-mirror] [PATCH] arm64: dts: msm8916: Correct ipc references for smsm

by Bjorn Andersson

SMSM is not symmetrical, the incoming bits from WCNSS are available at index 6, but the outgoing host id for WCNSS is 3. Further more, upstream references the base of APCS (in contrast to downstream), so the register offset of 8 must be included.

[Linux-stable-mirror] [PATCH 6/7] blk-mq: Rerun hardware queues after having called .put_budget()

by Bart Van Assche

During request dispatch, after a scheduler or per-CPU queue has been examined, .put_budget() is called if the examined queue is empty. Since a new request may be queued concurrently with the .put_budget() call, a request queue needs to be rerun after each .put_budget() call.
