Subject: [patch] 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 a u16 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.

This is a static checker thing.  I haven't tested it.  Please review
carefully.
