Subject: [ 02/11] Dove: Fix irq_to_pmu()
Date: Thu, 6 Dec 2012 16:56:58 -0800 [thread overview]
Message-ID: <20121207005613.930702915@linuxfoundation.org> (raw)
In-Reply-To: <20121207005613.189054768@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Russell King - ARM Linux <linux@arm.linux.org.uk>
commit d356cf5a74afa32b40decca3c9dd88bc3cd63eb5 upstream.
PMU interrupts start at IRQ_DOVE_PMU_START, not IRQ_DOVE_PMU_START + 1.
Fix the condition. (It may have been less likely to occur had the code
been written "if (irq >= IRQ_DOVE_PMU_START" which imho is the easier
to understand notation, and matches the normal way of thinking about
these things.)
