[PATCH 3.4-rc4] ARM: OMAP1: Amstrad Delta: Fix wrong IRQ base in FIQ handler

From: Janusz Krzysztofik
Date: Mon Apr 30 2012 - 13:27:19 EST


Commit 384ebe1c2849160d040df3e68634ec506f13d9ff, "gpio/omap: Add DT
support to GPIO driver", introduced dynamic IRQ numbering of OMAP GPIO
interrupts, breaking all IH_GPIO_BASE based IRQ number calculations.
This issue was corrected in the OMAP GPIO driver and the related header
file with commit 25db711df3258d125dc1209800317e5c0ef3c870, "gpio/omap:
Fix IRQ handling for SPARSE_IRQ".

However, the Amstrad Delta FIQ handler, which replaces the gpio-omap
driver in serving GPIO interrupts on this board, still uses that
outdated method. Fix it.

Created and tested against linux-3.4-rc4.
