From: Guennadi Liakhovetski <g.liakhovetski@xxxxxx> On platforms with no support for the shdma dmaengine driver build is currently failing with drivers/built-in.o: In function `sh_mobile_sdhi_probe': drivers/mmc/host/sh_mobile_sdhi.c:170: undefined reference to`shdma_chan_filter' Fix the breakage by defining shdma_chan_filter to NULL in such configurations.

It fixes a build problem on a number of shmobile defconfigs including bockw. Alternatively, I would be happy to take this through the renesas tree. I posted this patch last week but I'm wondering if you missed it somehow. This patch resolves a regression in v3.11-rc1. diff --git a/include/linux/shdma-base.h b/include/linux/shdma-base.h index 382cf71..5b1c984 100644 --- a/include/linux/shdma-base.h +++ b/include/linux/shdma-base.h @@ -124,6 +124,10 @@ void shdma_chan_remove(struct shdma_chan *schan); int shdma_init(struct device *dev, struct shdma_dev *sdev, int chan_num); void shdma_cleanup(struct shdma_dev *sdev); +#if IS_ENABLED(CONFIG_SH_DMAE_BASE) bool shdma_chan_filter(struct dma_chan *chan, void *arg); +#else +#define shdma_chan_filter NULL +#endif #endif -- 1.8.2.1 -- To unsubscribe from this list: send the line "unsubscribe linux-sh" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
