From 4aa05917051b01da037a80c3207b48aee252eed2 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Mon, 22 Feb 2010 08:38:36 +0200 Subject: [PATCH] wl1271: Don't mask interrupts while handling interrupt Don't mask firmware interrupts while processing interrupts. This allows the interrupt handler looping to work efficiently thus reducing interrupt processing latency. Signed-off-by: Juuso Oikarinen Reviewed-by: Teemu Paasikivi Signed-off-by: John W.
