This is a semi-automated conversion to change rt2x00usb_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:\(\<rt2x00usb_register_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
-i 's:\(\<rt2500usb_register_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
-i 's:\(\<rt2500usb_register_read_lock\>(.*, .*\), &\(.*\));:\2 = \1);:' \

This prepares the driver for changing all the 'read' register accessors
to return the value instead of passing it by reference. Since a lot
of them are used in callbacks, this takes care of the callbacks first,
adding a couple of helpers that will be removed again one at a time.
