Subject: mmc: core: remove redundant memset of mmc_decode_cid
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0076c71e37cc9f3f0b1c0c83f9f26f31a47222b0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mmc: core: remove redundant memset of mmc_decode_cid

When initializing sd or sdio card, we get struct mmc_card
from mmc_alloc_card which allocates it by kzalloc. So we don't
need another memset while decoding cid.
