Kristina Martsenko a31b0c6c19 mmc: core: fix card detection regression ... Since commit 89168b4899 ("mmc: core: restore detect line inversion semantics"), the SD card on i.MX28 (and possibly other) devices isn't detected and booting stops at: [ 4.120617] Waiting for root device /dev/mmcblk0p3... This is caused by the MMC_CAP2_CD_ACTIVE_HIGH flag being set incorrectly when the host controller doesn't use a GPIO for card detection (but instead uses a dedicated pin). In this case mmc_gpiod_request_cd() will return before assigning to the gpio_invert variable, leaving the variable uninitialized. The variable then gets used to set the flag. This patch fixes the issue by making sure gpio_invert is set to false when a GPIO isn't used. After this patch, i.MX28 boots fine. The MMC_CAP2_RO_ACTIVE_HIGH (write protect) flag is also set incorrectly for the exact same reason (it uses the same uninitialized variable), so this patch fixes that too.
