[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Six small and reasonably obvious fixes, all in drivers.

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

Bjorn Andersson (1):
      scsi: ufs: core: Drop loglevel of WriteBoost message

Changyuan Lyu (2):
      scsi: pm80xx: Set stopped phy's linkrate to Disabled
      scsi: pm80xx: Fix 'Unknown' max/min linkrate

Mike Christie (1):
      scsi: target: Fix WRITE_SAME No Data Buffer crash

Ming Lei (1):
      scsi: megaraid: Clear READ queue map's nr_queues

Po-Wen Kao (1):
      scsi: ufs: core: Fix missing clk change notification on host reset
