Subject: ASoC: tegra: Fix DSPK 16-bit playback
From: Sameer Pujar <spujar@xxxxxxxxxx>
commit 2e93a29b48a017c777d4fcbfcc51aba4e6a90d38 upstream.
DSPK configuration is wrong for 16-bit playback and this happens because
the client config is always fixed at 24-bit in hw_params(). Fix this by
updating the client config to 16-bit for the respective playback.
