From 9d3fde86b15303decea632c929fbf1f3ae4501f2 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 23 Sep 2013 16:27:32 +0200 Subject: [PATCH] backlight: atmel-pwm-bl: 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 a gpio_request fails.
