Hi!
This call to of_irq_find_parent breaks gpiolib-of for SPARC due to the
fact that the function is undefined when !defined(CONFIG_OF_IRQ) &&
defined(CONFIG_OF).
Defining the empty of_irq_find_parent in include/linux/of_irq.h when
!defined(CONFIG_OF_IRQ) instead of the current case when
!defined(CONFIG_OF) would solve the immediate compilation problem.
However, when !defined(CONFIG_OF_IRQ) (i.e. SPARC in this case) the
whole tree walking will never accomplish anything, so it would be good
if of_gpiochip_reserve_irq_lines is just an empty dummy or something
like that when !defined(CONFIG_OF_IRQ).
Cheers,
Andreas Larsson
