ar9003.c uninitialized variable

[David Hill]

Hello,

in file sys/dev/ic/ar9003.c, function ar9003_compute_predistortion(),
there is an uninitialized variable, y4.  It is then used:

        scale = ((y4 / SCALE_LOG) * (L + 1) -
                 (y2 / SCALE_LOG) * sumy2) * SCALE_LOG;

Email to damien and reyk have gone unanswered.  Anyone know what y4
should be set to?
