The patch titled
Subject: backlight: atmel-pwm-bl: use devm_gpio_request()
has been removed from the -mm tree. Its filename was
backlight-atmel-pwm-bl-use-devm_gpio_request.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: backlight: atmel-pwm-bl: use devm_gpio_request()
The devm_ functions allocate memory that is released when a driver
detaches. This patch uses devm_gpio_request() for these functions.
