sh: fix INTC to use set_irq_chained_handler() for redirects
This patch updates the shared INTC code to use set_irq_chained_handler() for intc_redirect_irq(). With this in place request_irq() on a merged irq which has been redirected will now return -EINVAL instead of 0 together with a crash. This thanks to the protection of the IRQ_NOREQUEST flag set for chained interrupt handlers. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
