Subject[086/136] ath5k: do not release irq across suspend/resume
2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Bob Copeland <me@bobcopeland.com>

commit 0d0cd72fa1e6bfd419c99478ec70b4877ed0ef86 upstream.

Paraphrasing Rafael J. Wysocki: "drivers should not release PCI IRQs
in suspend." Doing so causes a warning during suspend/resume on some
platforms.
