Revision d66eaf9f89502971fddcb0de550b01fa6f409d83 authored by Oleksij Rempel on 21 July 2013, 13:36:19 UTC, committed by Sarah Sharp on 25 July 2013, 15:10:09 UTC
in some cases where device is attched to xhci port and do not responding, for example ath9k_htc with stalled firmware, kernel will crash on ring_doorbell_for_active_rings. This patch check if pointer exist before it is used. This patch should be backported to kernels as old as 2.6.35, that contain the commit e9df17eb1408cfafa3d1844bfc7f22c7237b31b8 "USB: xhci: Correct assumptions about number of rings per endpoint" Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: stable@vger.kernel.org
