Subject: drivers:net: Remove dma_alloc_coherent OOM messages
X-Git-Tag: v3.12-rc1~874^2~451
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d0320f750093d012d3ed69fc1e8b385f654523d5;p=kernel%2Fkernel-generic.git

drivers:net: Remove dma_alloc_coherent OOM messages

I believe these error messages are already logged
on allocation failure by warn_alloc_failed and so
get a dump_stack on OOM.

Remove the unnecessary additional error logging.

Around these deletions:

o Alignment neatening.
o Remove unnecessary casts of dma_alloc_coherent.
o Hoist assigns from ifs.
