This is a semi-automated conversion to change rt2800_register_read to return the register contents instead of passing them by value, resulting in much better object code. The majority of the patch was done using: sed -i 's:\(rt2800_register_read(.*, .*\), &\(.*\));:\2 = \1);:' \ 's:\(rt2800_register_read_lock(.*, .*\), &\(.*\));:\2 = \1);:' \ drivers/net/wireless/ralink/rt2x00/rt2800lib.c The function itself was modified manually along with the one remaining multi-line caller that was not covered automatically and the indirect reference.
