Subject: [PATCH] ext2: le*_add_cpu conversion
Date: Wed, 13 Feb 2008 00:06:14 +0100	[thread overview]
Message-ID: <1202857582-15450-10-git-send-email-marcin.slusarz@gmail.com> (raw)
In-Reply-To: <1202857582-15450-1-git-send-email-marcin.slusarz@gmail.com>

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
