From 493cdec7ac68b6534f0dff1dd2e0d97c90930630 Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Wed, 13 May 2015 13:38:28 +0200 Subject: [PATCH] common: cmd pmic: command cleanup This commit cleanups the use of function: failed(). The new function name is: failure(), and it is used for print errno and the errno-related message only. The second change is choosing PMIC device by it's name, instead of seq number. Thanks to this change, for set the current device, call of pmic_get() is enough.
