Merge branch 'sh_eth-E-DMAC-interrupt-mask-cleanups'
Sergei Shtylyov says: ==================== sh_eth: E-DMAC interrupt mask cleanups Here's a set of 3 patches against DaveM's 'net-next.git' repo. The main goal of this set is to stop using the bare numbers for the E-DMAC interrupt masks. [1/3] sh_eth: rename EESIPR bits [2/3] sh_eth: add missing EESIPR bits [3/3] sh_eth: stop using bare numbers for EESIPR values ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
