Subject: mmc: core: remove redundant memset of sdio_read_cccr
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a0747eb81c1d106b1408d60452af75cd17a67621;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mmc: core: remove redundant memset of sdio_read_cccr

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