Subject: [PATCH] ufs: [bl]e*_add_cpu conversion

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

replace all:
big/little_endian_variable = cpu_to_[bl]eX([bl]eX_to_cpu(big/little_endian_variable) +
					expression_in_cpu_byteorder);
with:
	[bl]eX_add_cpu(&big/little_endian_variable, expression_in_cpu_byteorder);
generated with semantic patch
