ravb: read MAC address registers only once
The code reading the MAHR/MALR registers in ravb_read_mac_address() is terribly ineffective -- it reads MAHR 4 times and MALR 2 times, while it's enough to read each register only once. Use the local variables to achieve that, somewhat beautifying the code while at it... Signed-off-by:Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by:
