From 7be3b27f4110a453da662473546e653939dd8f70 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 20 Apr 2017 13:17:02 +0300 Subject: [PATCH] ASoC: Intel: Skylake: Uninitialized variable in probe_codec() [ Upstream commit e6a33532affd14c12688c0e9b2e773e8b2550f3b ] My static checker complains that if snd_hdac_bus_get_response() returns -EIO then "res" is uninitialized. Fix this by initializing it to -1 so that the error is handled correctly.
