From 575400bf5d57f53a767bc215bd709e65e5b27a5c Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Wed, 5 May 2010 22:12:20 +0000 Subject: [PATCH] net: emaclite: Use resource_size Use the resource_size function instead of manually calculating the resource size. This reduces the chance of introducing off-by-one errors. Signed-off-by: Tobias Klauser Signed-off-by: David S.
