Subject: [PATCH] wireless: iwlwifi3945/4965 - fix incorrect counting of memory
Date: Sat, 26 Jan 2008 19:09:36 +0300	[thread overview]
Message-ID: <20080126160936.GB6738@cvg> (raw)

This patch does fix incorrect counting of memory allocated by kmalloc.
It seems that could lead to allocated memory overrun and corrupt
nearlaid memory area.
