ASoC: qcom: sdm845: Add error handling in sdm845_slim_snd_hw_params()
commit 688abe2860fd9c644705b9e11cb9649eb891b879 upstream.
The function sdm845_slim_snd_hw_params() calls the functuion
snd_soc_dai_set_channel_map() but does not check its return
value. A proper implementation can be found in msm_snd_hw_params().
Add error handling for snd_soc_dai_set_channel_map(). If the
function fails and it is not a unsupported error, return the
error code immediately.
Fixes: 5caf64c633a3 ("ASoC: qcom: sdm845: add support to DB845c and Lenovo Yoga")
