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
Comment 1 Vasco Gervasi 2013-08-26 08:34:31 UTC 
Same error for me, but rc7 doesn't fix it.
Is there a patch to apply?
Comment 2 Vasco Gervasi 2013-08-27 14:58:49 UTC 
Same error with linux-next-20130827
Comment 3 Vasco Gervasi 2013-09-03 07:11:29 UTC 
Same error with 3.11.0 final release.
Comment 5 Vasiliy Glazov 2013-09-18 09:47:35 UTC 
Almost a month bug not solved. Now it present in 3.11.1 and I have kernel panic with it.
Comment 6 Vasco Gervasi 2013-09-18 09:50:33 UTC 
For me the patch posted here https://bugzilla.kernel.org/show_bug.cgi?id=61291 worked
