Subject: [PATCH v2 1/3] ALSA: hda: cs35l41: Correct error condition handling

From: Vitaly Rodionov <vitalyr@...nsource.cirrus.com>

Function cs_dsp_coeff_write_ctrl() can return 3 possible values:
0 - no change, 1 - value has changed and -1 - error, so positive value
is not an error.
Fixes: 7406bdbc4fb8 ("ASoC: wm_adsp: Return whether changed when writing controls")
