From d94ea3f6d21e8b4398285516cc307c81d7374ec9 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 6 Jun 2013 14:11:38 +0100 Subject: irqchip: Return -EPERM for reserved IRQs The irqdomain core will report a log message for any attempted map call that fails unless the error code is -EPERM. This patch changes the Versatile irq controller drivers to use -EPERM because it is normal for a subset of the IRQ inputs to be marked as reserved on the various Versatile platforms.
