From f23aa62545c18728eb2b9434aa258be27e07dd49 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 21 Nov 2011 16:46:24 -0500 Subject: caif: fix endian conversion in cffrml_transmit() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The "tmp" variable here is used to store the result of cpu_to_le16() so it should be an __le16 instead of an int. We want the high bits set and the current code works on little endian systems but not on big endian systems. Signed-off-by: Dan Carpenter Acked-by: Sjur Brændeland Signed-off-by: David S.
