You could vary the label by giving each one some compressed prefix based
on the name of the function it's in, a sort of poor man's namespacing ...

i915_do_some_stuff()
{
	...
	goto dss_exit;
	...

dss_exit:
	return ret;
}

i915_exciting_new_function()
{
	...
	goto enf_exit;
	...

enf_exit:
	return ret;
}

.Dave.
