Subject: [PATCH 0/3] ath9k: interrupt fixes on queue reset

Hi,

The following are two patches for ath9k to fix a potential interrupt
storm (PATCH 2/3) and to fix potentially resetting the wifi chip while
its interrupts were accidentally reenabled (PATCH 3/3).

PATCH 1/3 adds the possibility to trigger the ath9k queue reset through
the ath9k reset file in debugfs. Which was helpful to reproduce and debug
this issue and might help for future debugging.

PATCH 2/3 and PATCH 3/3 should be applicable for stable.

Regards, Linus
