   ASoC: Intel: Skylake: Disable clock gating during firmware and library download

has been applied to the asoc tree at

Subject: [PATCH] ASoC: Intel: Skylake: Disable clock gating during firmware
 and library download

During firmware and library download, sometimes it is observed that
firmware and library download is timed-out resulting into probe failure.

This patch disables dynamic clock gating while firmware and library
download.
