Subject: [PATCH -next] ASoC: rt5677: Fix build error without CONFIG_SPI
Date: Wed, 27 Nov 2019 16:21:45 +0800	[thread overview]
Message-ID: <20191127082145.6100-1-yuehaibing@huawei.com> (raw)

If CONFIG_SPI is n, SND_SOC_RT5677_SPI also is n, building fails:

sound/soc/codecs/rt5677.o: In function `rt5677_irq':
rt5677.c:(.text+0x2dbf): undefined reference to `rt5677_spi_hotword_detected'
sound/soc/codecs/rt5677.o: In function `rt5677_dsp_work':
rt5677.c:(.text+0x3709): undefined reference to `rt5677_spi_write'

This adds stub helpers to fix this.
