Subject: [patch 7/8] m68knommu: 5772: Replace private irq flow handler
Date: Wed, 02 Feb 2011 21:41:31 -0000	[thread overview]
Message-ID: <20110202212552.413849952@linutronix.de> (raw)
In-Reply-To: <20110202212258.546660886@linutronix.de>

[-- Attachment #1: m68knommu-replace-private-handler.patch --]
[-- Type: text/plain, Size: 1000 bytes --]

That handler lacks the minimal checks for action being zero etc. Keep
the weird flow - ack before handling - intact and call into
handle_simple_irq which does the right thing.
