Description Jouni Mettälä 2013-08-23 15:39:17 UTC 
Skge doesn't connect and shortly after failed try crashes too. Reverting this commit fixes both issues.

skge: add dma_mapping check
This old driver never checked for DMA mapping errors.
Causing splats with the new DMA mapping checks:
	WARNING: at lib/dma-debug.c:937 check_unmap+0x47b/0x930()
	skge 0000:01:09.0: DMA-API: device driver failed to check map

Same error for me, but rc7 doesn't fix it.
Is there a patch to apply?
