xen: Fix annoying compile-time warning
Commit cb6b6df111e4 ("xen/pv-on-hvm kexec: add quirk for Xen 3.4 and
shutdown watches.") added the xen_strict_xenbus_quirk() function with an
old K&R-style declaration without proper typing, causing gcc to rightly
complain:
drivers/xen/xenbus/xenbus_xs.c:628:13: warning: function declaration isn’t a prototype [-Wstrict-prototypes]
because we really don't live in caves using stone-age tools any more,
and the kernel has always used properly typed ANSI C function
declarations.
So if a function doesn't take arguments, we tell the compiler so
explicitly by adding the proper "void" in the prototype.
I'm sure there are tons of other examples of this kind of stuff in the
tree, but this is the one that hits my workstation config, so..
