From d295b129762bf6b2b7541243f496e363580de4a2 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 11 Jul 2012 08:05:05 +0200 Subject: pwm: fix used-uninitialized warning in pwm_get() Some versions of GCC don't seem no notice that the initialization of the index variable is tied to that of the chip variable and falsely report it as potentially being used uninitialized. However, to save anybody else from tripping over this, we now initialize the index variable unconditionally.
