[v3.11][Regression] skge: add dma_mapping check

[Joseph Salisbury]

Hi Stephen,

A bug was opened against the Ubuntu kernel[0].  A bug has also been
opened in bugzilla[1].  After a kernel bisect, it was found that
reverting the following commit resolved this bug:

commit 136d8f377e1575463b47840bc5f1b22d94bf8f63
Author: stephen hemminger <stephen@networkplumber.org>

    skge: add dma_mapping check


The regression was introduced as of v3.11-rc6.

I see that you are the author of this patch, so I wanted to run this by
you.  I was thinking of requesting a revert for v3.11, but I wanted to
get your feedback first.


Thanks,

Joe
