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. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.
