| Subject: dmaengine: shdma: fix a build failure on platforms with no DMA |
| support |
| |
| 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. |
