From 49df2b33478fd67e642d05786d06de322504842c Mon Sep 17 00:00:00 2001 From: Jes Sorensen <jes@sgi.com> Date: Fri, 26 Oct 2007 16:10:39 +0200 Subject: [PATCH] iwlwifi: disable interrupts before calling request_irq Disable interrupts in the iwl4965 before calling request_irq() for the case that the previous OS or the BIOS left a pending interrupt in the chip. This behavior has been observed on some laptops such as T61 Thinkpads and Toshiba Portege R500 Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: John W.
