[RFC PATCH 2/5] sh: Remove irq_reserve_irq calling

From: Yinghai Lu
Date: Sun Apr 06 2014 - 01:39:29 EST


in sh calling path:
register_intc_controller
==> irq_create_identity_mapping/irq_create_strict_mappins
==>irq_alloc_desc: it will set bits on allocate_irq
==> intc_register_irq
==> irq_reserve_irq: set bits again

so we can kill this irq_reserve_irq calling.
