Subject: [PATCH] ASoC: Intel: Skylake: Reset the controller in probe
Git-commit: 60767abcea3dd1d47a4bd38398e1e8c1864975eb
Patch-mainline: v4.14-rc1
References: bsc#1051510
Controller can be in reset state by default. Capability structure
traversal requires the controller to be out of reset else it
results in broken capability parsing. Hence make sure that controller is
out of reset before parsing capabilities by doing a full reset.
