Subject: [PATCH] affs: be*_add_cpu conversion

From: Marcin Slusarz <marcin.slusarz@...il.com>

replace all:
big_endian_variable = cpu_to_beX(beX_to_cpu(big_endian_variable) +
					expression_in_cpu_byteorder);
with:
	beX_add_cpu(&big_endian_variable, expression_in_cpu_byteorder);
generated with semantic patch
