From 23a895aee6081c144ffcc61eaf52dc62e10b3bd1 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Thu, 13 Sep 2012 21:48:14 +0200 Subject: [PATCH] pinctrl: use kasprintf() in pinmux_request_gpio() Instead of using a temporary buffer, snprintf() and kstrdup(), just use kasprintf() that does the same thing in just oneline.
