From d6a7c5c84f5ddab54717914ad293ed9d99d644ff Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Mon, 8 Sep 2014 17:54:57 -0700 Subject: [PATCH] arm: omap: irq: get rid of ifdef hack we don't need the ifdef if we have omap_nr_pending telling us how many pending registers we have on current platform. This solves a possible problem where we could try to handle bogus interrupts on OMAP2 and OMAP3 if using single zImage kernel, because we would end up reading the following pending FIQ register.
