Subject: [GIT PULL] SCSI fixes for 5.15-rc2
Thirty Three fixes, I'm afraid. Essentially the build up from the last
couple of weeks while I've been dealling with Linux Plumbers conference
infrastructure issues. It's mostly the usual assortment of spelling
fixes and minor corrections. The only core relevant changes are to the
sd driver to reduce the spin up message spew and fix a small memory
leak on the freeing path.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
