[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 <bunk@stusta.de> Signed-off-by: David S. Miller <davem@davemloft.net>
