linux-toradex.git/drivers/net/wireless, branch v3.2.55 Linux kernel for Apalis and Colibri modules ath9k: Fix interrupt handling for the AR9002 family 2014-02-15T19:20:14+00:00 Sujith Manoharan c_manoha@qca.qualcomm.com 2013-12-16T01:34:59+00:00 5982c7fe4acf612e50738475c2c7f2eb47ec7ec2 commit 73f0b56a1ff64e7fb6c3a62088804bab93bcedc2 upstream. This patch adds a driver workaround for a HW issue. A race condition in the HW results in missing interrupts, which can be avoided by a read/write with the ISR register. All chips in the AR9002 series are affected by this bug - AR9003 and above do not have this problem.
