Subject: [PATCH v2 04/10] rt2x00: convert rt2x00mmio_register_read return type
This is a semi-automated conversion to change rt2x00mmio_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:\(rt2x00mmio_register_read(.*, .*\), &\(.*\));:\2 = \1);:' \
-i 's:_rt2x00mmio_register_read:rt2x00mmio_register_read:' \
drivers/net/wireless/ralink/rt2x00/*.c
The function itself was modified manually along with the one remaining
caller that was not covered automatically.
