From: Fabio Estevam Date: Tue, 7 Oct 2014 13:50:56 +0000 (-0300) Subject: ASoC: sgtl5000: Cleanup the comments X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7f6d75d77683c8f9c18836a2fea2a1e76efc3a9a;p=linux-beck.git ASoC: sgtl5000: Cleanup the comments Fix grammar and typos. Besides that, also fix the comment about the range of SYS_MCLK, which is from 8 to 27 MHz.
