Message-Id: <1434013569-24745-2-git-send-email-alexandre.belloni@free-electrons.com> Date: Thu, 11 Jun 2015 11:06:09 +0200 From: Alexandre Belloni <alexandre.belloni@...e-electrons.com> To: Nicolas Ferre <nicolas.ferre@...el.com>, Mark Brown <broonie@...nel.org> Cc: alsa-devel@...a-project.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Alexandre Belloni <alexandre.belloni@...e-electrons.com> Subject: [PATCH 2/2] ASoC: atmel: properly select dma driver state It is currently possible to have CONFIG_SND_ATMEL_SOC_SSC=y with either CONFIG_SND_ATMEL_SOC_PDC=m or CONFIG_SND_ATMEL_SOC_DMA=m. This results in a driver that compiles but does not link with this kind of error: sound/built-in.o: In function `atmel_ssc_set_audio': (.text+0x87d90): undefined reference to `atmel_pcm_pdc_platform_register' sound/built-in.o: In function `atmel_ssc_put_audio': (.text+0x8879a): undefined reference to `atmel_pcm_pdc_platform_unregister' Introduce new config options SND_ATMEL_SOC_SSC_PDC and SND_ATMEL_SOC_SSC_DMA which should be used by the board drivers and the correct logic to properly select the SND_ATMEL_SOC_PDC and SND_ATMEL_SOC_DMA states.
