misc: carma: fixup return type of wait_for_completion_timeout
return type of wait_for_completion_timeout is unsigned long not int. The rc variable is renamed timeout to reflect its use and the type adjusted to unsigned long. Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
