[alsa-devel] [PATCH] ALSA: hda - fixup ALC262 to skip depop delay before D3 on Intel BayleyBay

[mengdong.lin at intel.com]

From: Mengdong Lin <mengdong.lin at intel.com>

This patch sets a 0ms depop delay in fixup funtion 'alc_fixup_no_depop_delay'.
And Realteck ALC262 applies this on Intel Baytrail BayleyBay platform to reduce
codec suspend time.
