Why the rush? The behaviour of the cros_ec_cmd_xfer() function has not
changed in at least a year, so this can't be very urgent. I merged the
original patch because it is a dependency for another patch, but given
the above I think it's fine if we wait until after v4.8-rc1 and let
subsystem maintainers pick them up individually.

On another note, the commit message makes it sound like this might fix
potential bugs. Since it's been like that for a couple of releases, do
we need to Cc: stable@vger.kernel.org?
