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.
Is this a bug and should be fixed ?
Well, at least as soon as anyone tries to use in a context that does not
exclude SPARC it creates a bug, so I would say so. There is no reason
for SPARC to fall between the chairs. This is the first case I am aware
of that triggers this.
Cheers,
Andreas
