[PATCH 2/5] ASoC: wm_adsp: Use cs_dsp_coeff_lock_and_[read|write]_ctrl()

From: Richard Fitzgerald
Date: Mon Mar 25 2024 - 10:55:39 EST


From: Simon Trimmer <simont@xxxxxxxxxxxxxxxxxxxxx>

Using the cs_dsp_coeff_lock_and_[read|write]_ctrl() wrappers tidies
the calling functions as it does not need to manage the DSP pwr_lock.
