linux-next/include/linux/reset.h
Hans de Goede e3ec0a8c6e reset: Add of_reset_control_get to reset.h
of_reset_control_get is not declared static in drivers/reset/core.c, which
is correct as we want to use it elsewhere too. But it does not have a
protype declared anywhere under include/linux. Add a prototype / stub for it
to linux/reset.h to fix this.
