From: Sodhi, VunnyX Date: Fri, 28 Oct 2016 11:29:41 +0000 (+0530) Subject: ASoC: Intel: Skylake: Fix to turn off hdmi power on probe failure X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7a5857c3c282c12a8bd0cfd2dd4a17a9252c2b4d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ASoC: Intel: Skylake: Fix to turn off hdmi power on probe failure HDMI codec is required to be powered up before controller initialization for successful enumeration of codec. If the probe fails it needs to be powered off to balance the power state of HDMI codec. This fix balances the reference count in the error path before turning off the codec.
