category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8ZD3X
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.10.207&id=cea19678bf55f8d087bf617478f249208432156c

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

This reverts commit f2d30198c0530b8da155697d8723e19ac72c15fe which is
commit bf23e619 upstream.

As reported, a lot of scsi changes were made just to resolve a 2 line
patch, so let's revert them all and then manually fix up the 2 line
fixup so that things are simpler and potential abi changes are not an
issue.
