Message-Id: <1410905274-22339-1-git-send-email-linus.walleij@linaro.org> Date: Tue, 16 Sep 2014 15:07:54 -0700 From: Linus Walleij <linus.walleij@...aro.org> To: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Cc: linux-gpio@...r.kernel.org, Linus Walleij <linus.walleij@...aro.org> Subject: [PATCH] pinctrl: 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.
