Subject: ASoC: Avoid writing to WM8971_RESET in wm8971_resume
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1a3bbb40da5c01e422309f52475e91886c573718;p=linux-beck.git

ASoC: Avoid writing to WM8971_RESET in wm8971_resume

Writing to WM8971_RESET resets all registers to the default state.
Thus we should avoid writing to WM8971_RESET on resume.
