mmc: sdio: don't reinitialize nonremovable powered-resumed cards
Upon system resume, SDIO core must reinitialize cards that were powered off during suspend. If the card had its power kept during suspend (and thus it is 'powered-resumed'), SDIO core performs only a limited reinitializing, mainly needed to make sure that the card wasn't removed/replaced. If a __nonremovable__ card is powered-resumed, we can safely skip the reinitializing phase. Note: 9b966aa (mmc: sdio: fully reconfigure oldcard on resume) removed the bus width reconfiguration since mmc_sdio_init_card already does it. It is brought back now in case mmc_sdio_init_card is skipped. Signed-off-by: Ohad Ben-Cohen <ohad@wizery.com> Signed-off-by: Chris Ball <cjb@laptop.org>
