Date: Sat, 7 Dec 2013 14:08:53 +0100 From: Alexandre Belloni <alexandre.belloni@...e-electrons.com> To: Jean-Christophe Plagniol-Villard <plagnioj@...osoft.com> Cc: Nicolas Ferre <nicolas.ferre@...el.com>, linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, Linus Walleij <linus.walleij@...aro.org>, Alexandre Belloni <alexandre.belloni@...e-electrons.com> Subject: [PATCH 2/3] pinctrl: at91: initialize config parameter to 0 When passing a not initialized config parameter, at91_pinconf_get() would return a bogus value. Fix that by initializing it to zero before using it.
