[patch 61/62] ath5k: dont enable MSI, we cannot handle it yet

[Greg KH]

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

------------------
From: Pavel Roskin <proski@xxxxxxx>

commit 256b152b005e319f985f50f2a910a75ba0def74f upstream

MSI is a nice thing, but we cannot enable it without changing the
interrupt handler.  If we do it, we break MSI capable hardware,
specifically AR5006 chipset.
