Subject: [PATCH] ASoC: cirrus: i2s: Fix LRCLK configuration
Git-commit: 2d534113be9a2aa532a1ae127a57e83558aed358
Patch-mainline: v4.18-rc1
References: bsc#1051510
The bit responsible for LRCLK polarity is i2s_tlrs (0), not i2s_trel (2)
(refer to "EP93xx User's Guide").
Previously card drivers which specified SND_SOC_DAIFMT_NB_IF actually got
SND_SOC_DAIFMT_NB_NF, an adaptation is necessary to retain the old
behavior.
