[PATCH 5.5 104/120] ASoC: soc-generic-dmaengine-pcm: Fix error handling

From: Greg Kroah-Hartman
Date: Thu Feb 13 2020 - 10:39:16 EST


From: Shengjiu Wang <shengjiu.wang@xxxxxxx>

commit 130128098a4e5ce9a0dfbdf9a7e27a43579901fd upstream.

Remove the return value checking, that is to align with the code
before adding snd_dmaengine_pcm_refine_runtime_hwparams function.

Otherwise it causes a regression on the HiKey board:

[ 17.721424] hi6210_i2s f7118000.i2s: ASoC: can't open component f7118000.i2s: -6
