Subject: mmc: sdricoh_cs: remove redundant check if len is non-zero
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=675a7da857146338d047d1a63247bb48e7d5fed5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mmc: sdricoh_cs: remove redundant check if len is non-zero

At the end of either of the read or write loops len is always zero
and hence the non-zero check on len and return of -EIO is redundant
and can be removed.
