Subject: scsi: vmw_pvscsi: No need to clear memory after a dma_alloc_coherent() call
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0848ccaea664970e559d99348484615ba0f7ab63;p=linux.git

scsi: vmw_pvscsi: No need to clear memory after a dma_alloc_coherent() call

dma_alloc_coherent() already clear the allocated memory, there is no need
to explicitly call memset().

Since 'config_page' and 'header' are the same, a memset() call can be
avoided.
