| Subject: ath5k: write PCU registers on initial reset |
| |
| From: Bob Copeland <me@bobcopeland.com> |
| |
| 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. |
