[PATCH 5.10 048/167] ASoC: wm_adsp: Correct wm_coeff_tlv_get handling

From: Greg Kroah-Hartman
Date: Mon Jul 26 2021 - 12:17:53 EST

From: Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxx>

[ Upstream commit dd6fb8ff2210f74b056bf9234d0605e8c26a8ac0 ]

When wm_coeff_tlv_get was updated it was accidentally switch to the _raw
version of the helper causing it to ignore the current DSP state it
should be checking. Switch the code back to the correct helper so that
users can't read the controls when they arn't available.
