Subject[RFC PATCH 1/2] mmc: core: sdio: move mmc_sdio_init_card to a separate function
Date
No functional change. Move mmc_sdio_init_card to a separate
function (_mmc_sdio_power_restore) and invoke it from
mmc_sdio_power_restore. This is in preparation to invoke
_mmc_sdio_power_restore from mmc_sdio_runtime_resume so that
mmc_claim_host can be invoked before mmc_power_up.
