Subject: [PATCH] ASoC: mediatek: mtk-btcvsd: Add checks for write and read of mtk_btcvsd_snd
Date: Wed, 16 Nov 2022 11:07:50 +0800	[thread overview]
Message-ID: <20221116030750.40500-1-jiasheng@iscas.ac.cn> (raw)

As the mtk_btcvsd_snd_write and mtk_btcvsd_snd_read may return error,
it should be better to catch the exception.

Fixes: 4bd8597dc36c ("ASoC: mediatek: add btcvsd driver")
