[patch 04/24] ath5k: write PCU registers on initial reset

[Greg KH]

2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Bob Copeland <me@xxxxxxxxxxxxxxx>

commit 3355443ad7601991affa5992b0d53870335af765 upstream.

"Ath5k: unify resets"
introduced a regression into 2.6.28 where the PCU registers are never
initialized, due to ath5k_reset() always passing true for change_channel.
We subsequently program a lot of these registers but several may start
in an unknown state.
