Message-ID: <Pine.LNX.4.64.0810301304300.6842@melkki.cs.Helsinki.FI>
Date: Thu, 30 Oct 2008 13:04:58 +0200 (EET)
From: Pekka J Enberg <penberg@...helsinki.fi>
To: Greg Kroah-Hartman <greg@...ah.com>

Subject: [PATCH 2/3] w35und: remove some dead code
From: Pekka Enberg <penberg@...helsinki.fi>
This patch removes the WBLinux_ReceivePacket(), WBLINUX_GetNextPacket(),
WBLINUX_GetNextPacketCompleted, and sme_get_rssi() functions, which execute
BUG() unconditionally, and related dead code.
