Subject: [PATCH 5.4 13/62] ASoC: cs42l42: Dont allow SND_SOC_DAIFMT_LEFT_J

From: Richard Fitzgerald <rf@...nsource.cirrus.com>

[ Upstream commit 64324bac750b84ca54711fb7d332132fcdb87293 ]

The driver has no support for left-justified protocol so it should
not have been allowing this to be passed to cs42l42_set_dai_fmt().

Fixes: 2c394ca79604 ("ASoC: Add support for CS42L42 codec")
