From fb3194413d1ef79732931a40f54da21a16505a76 Mon Sep 17 00:00:00 2001 From: YueHaibing Date: Wed, 27 Nov 2019 16:21:45 +0800 Subject: [PATCH] ASoC: rt5677: Fix build error without CONFIG_SPI 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.
