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.
