Subject: pd: don't check blk_execute_rq return value.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=75a500ef6ecb6266d4d1347fc7eb4b298b566b3b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

pd: don't check blk_execute_rq return value.

The driver never sets req->errors, so blk_execute_rq will always return 0.
