From: Timur Tabi Date: Mon, 2 Feb 2009 21:08:29 +0000 (-0600) Subject: ASoC: fix message display in CS4270 codec driver X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a6c255e0945160b76eabe983f59e2129e0c66246;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ASoC: fix message display in CS4270 codec driver Replace printk calls with dev_xxx calls. Set the 'dev' field of the codec and codec_dai structures so that these calls work.
