Subject: [PATCH -next] ASoC: mediatek: Make some symbols static
Date: Wed, 29 May 2019 23:04:37 +0800	[thread overview]
Message-ID: <20190529150437.19004-1-yuehaibing@huawei.com> (raw)

Fix sparse warnings:

sound/soc/mediatek/common/mtk-btcvsd.c:410:5: warning: symbol 'mtk_btcvsd_write_to_bt' was not declared. Should it be static?
sound/soc/mediatek/common/mtk-btcvsd.c:698:9: warning: symbol 'mtk_btcvsd_snd_read' was not declared. Should it be static?
sound/soc/mediatek/common/mtk-btcvsd.c:779:9: warning: symbol 'mtk_btcvsd_snd_write' was not declared. Should it be static?
