From: Geert Uytterhoeven Date: Thu, 16 Jun 2016 12:34:31 +0000 (+0200) Subject: ASoC: ak4613: Implement suspend callback X-Git-Tag: v4.8-rc1~29^2~7^2~10^5 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=f9ae17ba97e0fd134f7c0108c70e708313a07063;p=linux-2.6-block.git ASoC: ak4613: Implement suspend callback Add the suspend callback to accompany the existing resume operation. With the suspend/resume callbacks the regmap (regcache) state handling can follow the recommended sequence. Based on commit a2ebd58627e9aa48 ("ASoC: ak4642: Implement suspend callback") by Peter Ujfalusi .
