From 1f8a5fb80e63aab63de81169ab749d73e7509e3f Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Tue, 19 Dec 2006 19:36:32 -0800 Subject: [PATCH] [ATM] drivers/atm/fore200e.c: Cleanups. This patch contains the following transformations from custom functions to standard kernel version: - fore200e_kmalloc() -> kzalloc() - fore200e_kfree() -> kfree() - fore200e_swap() -> cpu_to_be32() Signed-off-by: Adrian Bunk Signed-off-by: David S.
