From 88b1c01fb42e3d637c7e7f36cd4a30ce39a2add4 Mon Sep 17 00:00:00 2001 From: Nicolin Chen Date: Wed, 8 Jun 2016 16:10:05 -0700 Subject: [PATCH] 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.
