Subject: mmc: mvsdio: fix deferred probe from __init
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1867adee6ed7793a256ecdd623e1337988223c09;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

mmc: mvsdio: fix deferred probe from __init

Move probe out of __init section and don't use platform_driver_probe
which cannot be used with deferred probing.

Since commit e9354576 ("gpiolib: Defer failed gpio requests by default")
this driver might return -EPROBE_DEFER if the mmc_gpio_request_cd fails.
