Hi Martin,

Sporadic crashes have been observed with the UFS kernel driver if a timeout
occurs. This patch series fixes these crashes. Please consider this patch
series for the next merge window.

Thanks,

Bart.

Changes compared to v1: fixed a build error in the MediaTek driver.

Bart Van Assche (4):
  scsi: ufs: Declare ufshcd_mcq_poll_cqe_lock() once
  scsi: ufs: Make ufshcd_poll() complain about unsupported arguments
  scsi: ufs: Make the polling code report which command has been
    completed
  scsi: ufs: Check for completion from the timeout handler
