From 86c1a219c256a471535e360efc31611e1ae73a92 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 21 Dec 2015 16:29:50 +0100 Subject: pinctrl: spmi-gpio: Be sure to clamp return value MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern. Cc: Ivan T.
