Merge branch 'sh_eth-sw-reset'
Sergei Shtylyov says: ==================== sh_eth: couple of software reset bit cleanups Here's a set of 2 patches against DaveM's 'net-next.git' repo. We can save on the repetitive chip reset code... [1/2] sh_eth: call sh_eth_tsu_write() from sh_eth_chip_reset_giga() [2/2] sh_eth: reuse sh_eth_chip_reset() ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
