Subject: mmc: sh_mmcif: Enable MMC_CAP2_NO_SD and MMC_CAP2_NO_SDIO
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dab3a28b4005ecf4b6b380a8929c36de2c07a175;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mmc: sh_mmcif: Enable MMC_CAP2_NO_SD and MMC_CAP2_NO_SDIO

Enable the capabilities which tells the mmc core to prevent sending SD and
SDIO commands during card initialization. In this way, we can also remove
the validation of non-supported commands in the ->request() callback.
