From: Dan Carpenter Date: Mon, 21 Nov 2011 21:46:24 +0000 (-0500) Subject: caif: fix endian conversion in cffrml_transmit() X-Git-Tag: MMI-PSA29.97-13-9~17939^2~50 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f23aa62545c18728eb2b9434aa258be27e07dd49;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git caif: fix endian conversion in cffrml_transmit() 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.
