um: port_kern: fix -Wmissing-variable-declarations
I'm looking to enable -Wmissing-variable-declarations behind W=1. 0day
bot spotted the following instance:
arch/um/drivers/port_kern.c:147:14: warning: no previous extern
declaration for non-static variable 'port_work'
[-Wmissing-variable-declarations]
DECLARE_WORK(port_work, port_work_proc);
^
arch/um/drivers/port_kern.c:147:1: note: declare 'static' if the
variable is not intended to be used outside of this translation unit
DECLARE_WORK(port_work, port_work_proc);
^
This symbol is not referenced by more than one translation unit, so give
it static storage.
