[PATCH 4/7] pcmcia: at91_cf: fix deferred probe from __init
From: Johan Hovold
Date: Mon Sep 23 2013 - 10:29:16 EST
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 a gpio_request fails.
