ASoC: wm_adsp: Cancel ongoing work when removing controls
Removes wm_adsp_ctl_work and integrates the work_struct into wm_coeff_ctl so it may be referenced. Signed-off-by: Simon Trimmer <simont@opensource.cirrus.com> Link: https://lore.kernel.org/r/20210913160057.103842-5-simont@opensource.cirrus.com Signed-off-by: Mark Brown <broonie@kernel.org>
