Subject: [PATCH] ASoC: rt5640: Remove the sysclk and sysclk_src checking
Git-commit: d9c5996ab37fca71b4d97440798d54dd87540c8b
Patch-mainline: v5.18-rc1
References: jsc#PED-850
Remove the sysclk and sysclk_src checking in the function set_sysclk() to
prevent the PLL power off. It is not getting re-programmed during
subsequent runs after the first run (in BIAS_OFF stage).
