From 6f3b7ff4e309031e15402b71891b57eb14951b7a Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Sat, 24 Jan 2015 12:14:52 +0200 Subject: [PATCH] ath10k: disable irqs after fw crash It makes little sense to keep handling irqs if fw is dead. This prevents multiple fw register dumps upon crash on some devices (seen on QCA6174).
