Subject: ext2: le*_add_cpu conversion
X-Git-Tag: v2.6.26-rc1~766
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=fba4d3997f4c3dc6de927f7f516168580033ae1a;p=linux-2.6-omap-h63xx.git

ext2: le*_add_cpu conversion

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
