From e3d5af56e1a50c9bc3c24810e6b25df91d37bc77 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Mon, 12 Dec 2011 15:15:08 -0800 Subject: [PATCH] brcm80211: smac: remove ai_switch_core() function The function ai_switch_core() is no longer needed and its counterpart ai_restore_core() as well, because interrupts disabling is not needed anymore.
