genirq: export handle_edge_irq() and irq_to_desc()
Export handle_edge_irq() and irq_to_desc() to modules to allow them to
do things such as
__irq_set_handler_locked(...., handle_edge_irq);
This fixes
ERROR: "handle_edge_irq" [drivers/gpio/gpio-pch.ko] undefined!
ERROR: "irq_to_desc" [drivers/gpio/gpio-pch.ko] undefined!
when gpio-pch is being built as a module.
This was introduced by commit df9541a60af0 ("gpio: pch9: Use proper flow
type handlers") that added
__irq_set_handler_locked(d->irq, handle_edge_irq);
but handle_edge_irq() was not exported for modules (and inlined
__irq_set_handler_locked() requires irq_to_desc() exported as well)
