From b381fa3229a30f6d7b0e6053314c4a5378c9389d Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 12 Apr 2012 22:35:58 +0200 Subject: [PATCH] ath9k: optimize the hardware hang check Since it's only called when beacons are stuck, move it to the SWBA handler tasklet, to avoid doing redundant checks on every single interrupt.
