Subject: [patch 3/8] genirq: Do not fiddle with IRQ_MASKED in handle_edge_irq()
Date: Wed, 02 Feb 2011 21:41:17 -0000	[thread overview]
Message-ID: <20110202212551.918484270@linutronix.de> (raw)
In-Reply-To: <20110202212258.546660886@linutronix.de>

[-- Attachment #1: genirq-remove-redundant-mask.patch --]
[-- Type: text/plain, Size: 728 bytes --]

IRQ_MASKED is set in mask_ack_irq() anyway. Remove it from
handle_edge_irq() to allow simpler ab^HHreuse of that function.
