stable inclusion
from stable-5.10.52
commit 7207cd708eb3f59d7f7a7125604512089419a5d8
bugzilla: 175542 https://gitee.com/openeuler/kernel/issues/I4DTKU

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=7207cd708eb3f59d7f7a7125604512089419a5d8

--------------------------------

[ Upstream commit 7e26e3ea ]

scsi_execute() will now return a negative error if there was an error prior
to command submission; evaluate that instead if checking for DRIVER_ERROR.

[mkp: build fix]
