3.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ionut Nicu <ioan.nicu.ext@xxxxxxx> commit 250ad590d6f12d93f4d85be305b0a598d609232e upstream. Some gpio chips may have get/set operations that can sleep. gpio_set_value() only works for chips which do not sleep, for the others we will get a kernel warning. Using gpio_set_value_cansleep() will work for both chips that do sleep and those who don't.
