drivers:net: dma_alloc_coherent: use __GFP_ZERO instead of memset(, 0)
Reduce the number of calls required to alloc a zeroed block of memory. Trivially reduces overall object size. Other changes around these removals o Neaten call argument alignment o Remove an unnecessary OOM message after dma_alloc_coherent failure o Remove unnecessary gfp_t stack variable Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.
