Date: Wed, 21 Oct 2015 20:33:05 +0800 From: Jie Yang <yang.jie@...el.com> To: broonie@...nel.org Cc: alsa-devel@...a-project.org, rdunlap@...radead.org, sfr@...b.auug.org.au, liam.r.girdwood@...el.com, yang.jie@...el.com, linux-next@...r.kernel.org, linux-kernel@...r.kernel.org, vinod.koul@...el.com Subject: [PATCH] ASoC: Intel: sst: only use sst-firmware when DW DMAC is available Currentlly, we use Synopsys DesignWare DMA Controller for baytrail/haswell/broadwell ADSP firmware loading, but for skylake, we don't use it, compiling sst-firmware.c may introduce error when CONFIG_DW_DMAC_CORE is not enabled: sound/built-in.o: In function `sst_dma_new': (.text+0xd7b38): undefined reference to `dw_dma_probe' sound/built-in.o: In function `sst_dma_free': (.text+0xd7c0a): undefined reference to `dw_dma_remove' Here we only compile sst-firmware when CONFIG_DW_DMAC_CORE is selected, to fix the linking error issue.
