From: Nicolin Chen Date: Wed, 8 Jun 2016 23:10:05 +0000 (-0700) Subject: ASoC: cs53l30: Correct clock inversion check X-Git-Tag: v4.8-rc1~84^2~1^2~8^2~5 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=88b1c01fb42e3d637c7e7f36cd4a30ce39a2add4;p=karo-tx-linux.git ASoC: cs53l30: Correct clock inversion check SND_SOC_DAIFMT_IB_NF = 0x3 (11b) | SND_SOC_DAIFMT_IB_IF = 0x4 (100b) creates a mask 0x7 (111b) which also includes SND_SOC_DAIFMT_NB_IF = 0x2 (10b). So this patch uses the traditional way to check the clock inversion.
