Subject: [PATCH] scsi: sd: Improve unaligned completion resid message
Git-commit: 670d8be28e72f984a61ccad3e9e98247c0d31e1c
Patch-mainline: v5.4-rc1
References: bsc#1156419,jsc#SLE-8281
For commands completing with a resid not aligned on the device logical
sector size, also print the command CDB in addition to the current message
to help debug hardware generating such incorrect command completion
information.
