From 3069168c82d65f88e4ac76eda09baff02adfd743 Mon Sep 17 00:00:00 2001 From: Pavel Roskin Date: Wed, 31 Mar 2010 18:05:31 -0400 Subject: [PATCH] ath9k: move imask from sc to ah Add ah variable in the functions that didn't have it and used sc->imask. Replace sc->sc_ah with ah in those functions. Signed-off-by: Pavel Roskin Signed-off-by: John W.
