The assignment of the else and else if branches is the same, so the else
if here is redundant, so we remove it and add a comment to make the code
here readable.
./drivers/net/wireless/ralink/rt2x00/rt2800lib.c:8927:9-11: WARNING: possible condition with no effect (if == else).

I don't see how this comment is useful. Better to remove. One way or
another:
