From be9c00295b34760ea2f9667929049f094116b5a8 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 24 May 2012 19:10:45 +0900 Subject: sh: intc: Kill off deprecated dynamic IRQ API. Now that all of the users have been converted away, kill off the remnants of the old API.

This switches to using irq_alloc_desc() directly for subgroup IRQs. We still need to call activate_irq() on these in order to make them requestable, at least up until these get moved in to their own irq domain..
