Hi Arjan,

The original get_gpio_by_name() is static and only used in mrst.c as it's
mrst/mfld specific. So if we call it from a PCI driver, that name sounds
like a platform independent general API while it's actually mrst/mfld bound.
So we would show this dependency from the function name.

Thanks,
Feng
