From da26d5d803e45a30c7d72b83ce906f3a466f4cc3 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 16 Sep 2014 15:11:41 -0700 Subject: [PATCH] gpio: remove remaining users of gpiochip_remove() retval Some drivers accidentally still use the return value from gpiochip_remove(). Get rid of them so we can simplify this function and get rid of the return value.
