From cf44066a3836847a74f6a0817c680726b796239f Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Thu, 9 Feb 2012 21:09:07 +0100 Subject: [PATCH] brcm80211: fmac: use spinlock calls saving irq flags in brcmf_enq_event() This function is executed within irq context. The call spin_unlock_irq does enable interrupts which is not desired in the irq context. This patch replaces them using the spin_loc_irqsave and spin_unlock_irqrestore functions.
