Subject: [PATCH] dm integrity: fix error code in dm_integrity_ctr()
Git-commit: d3f2a14b8906df913cb04a706367b012db94a6e8
Patch-mainline: v5.19-rc1
References: git-fixes
The "r" variable shadows an earlier "r" that has function scope. It
means that we accidentally return success instead of an error code.
Smatch has a warning for this:
drivers/md/dm-integrity.c:4503 dm_integrity_ctr()
warn: missing error code 'r'
Fixes: 7eada909bfd7 ("dm: add integrity target")
