The subsystems regulator, clk and gpio have the concept of a dummy
resource. For regulator, clk and gpio there is a semantic difference
between the regular _get() function and the _get_optional() variant.
(One might return the dummy resource, the other won't. Unfortunately
which one implements which isn't the same for these three.) The
difference between platform_get_irq() and platform_get_irq_optional() is
only that the former might emit an error message and the later won't.

   This is only a current difference but I'm still going to return 0 ISO
-ENXIO from latform_get_irq_optional(), no way I'd leave that -ENXIO there

   platform.

   Grr, my mail server tossed it into the spam folder... :-(
