Merge patch series "Eight small UFS patches"

Browse Source 
Bart Van Assche <bvanassche@acm.org> says:

Hi Martin,

This patch series includes two bug fixes for this development cycle
and six small patches that are intended for the next merge window. If
applying the first two patches only during the current development
cycle would be inconvenient, postponing all patches until the next
merge window is fine with me.

Please consider including these patches in the upstream kernel.

Thanks,

Bart.

[mkp: Applied patches #1 and #2 to 6.18/scsi-fixes]
