Subject: ASoC: Intel: Skylake: Uninitialized variable in probe_codec()

From: Dan Carpenter <dan.carpenter@oracle.com>


[ 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.
