Subject: [PATCH] ntfs: le*_add_cpu conversion

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

replace all:
little_endian_variable = cpu_to_leX(leX_to_cpu(little_endian_variable) +
					expression_in_cpu_byteorder);
with:
	leX_add_cpu(&little_endian_variable, expression_in_cpu_byteorder);
generated with semantic patch
