Subject: ASoC: Do a warm reset after cold when resetting the WM9713
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e775f6c0fb6ac25ab8845d4ad1e17b4b015487f0;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ASoC: Do a warm reset after cold when resetting the WM9713

The WM9713 comes out of cold reset in low power mode so always requires
a warm reset to bring up the AC97 link after a cold reset.
