Subject: [PATCH] ASoC: rt5659: Update MCLK rate in set_sysclk()
Git-commit: dbf54a9534350d6aebbb34f5c1c606b81a4f35dd
Patch-mainline: v5.12-rc4
References: git-fixes

Simple-card/audio-graph-card drivers do not handle MCLK clock when it
is specified in the codec device node. The expectation here is that,
the codec should actually own up the MCLK clock and do necessary setup
in the driver.
