From abdc08a3a263a20e49534a36291d657bf53dda5b Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Tue, 19 Aug 2014 10:06:09 -0700 Subject: gpio: change gpiochip_request_own_desc() prototype The current prototype of gpiochip_request_own_desc() requires to obtain a pointer to a descriptor. This is in contradiction to all other GPIO request schemes, and imposes an extra step of obtaining a descriptor to drivers. Most drivers actually cannot even perform that step since the function that does it (gpichip_get_desc()) is gpiolib-private. Change gpiochip_request_own_desc() to return a descriptor from a (chip, hwnum) tuple and update users of this function (currently gpiolib-acpi only).
