From 1e9f954516ee03251e0ac2e98cad2e4be6ce9958 Mon Sep 17 00:00:00 2001 From: Konstantin Khlebnikov Date: Fri, 14 Dec 2012 01:03:03 +0000 Subject: [PATCH] mac802154: fix destructon ordering for ieee802154 devices mutex_destroy() must be called before wpan_phy_free(), because it puts the last reference and frees memory. Catched as overwritten poison in kmalloc-2048. Signed-off-by: Konstantin Khlebnikov Cc: Alexander Smirnov Cc: Dmitry Eremin-Solenikov Cc: David S.
