irqchip/mbigen: Checking for IS_ERR() instead of NULL
of_platform_device_create() returns NULL on error, it never returns error pointers. Fixes: ed2a1002d25c ('irqchip/mbigen: Handle multiple device nodes in a mbigen module') Acked-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
