Subject[PATCH] scsi: le*_add_cpu conversion
Date
From
From: Marcin Slusarz <marcin.slusarz@gmail.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
