Subject: [PATCH] irqdomain: fix irq_domain_xlate_onetwocell()
Date: Tue, 2 Aug 2016 10:52:45 +0200 [thread overview]
Message-ID: <57A05F5D.103@laposte.net> (raw)
Use IRQ_TYPE_SENSE_MASK on irq_domain_xlate_onetwocell()
According to the xlate() callback definition, the 'out_type' parameter
needs to be the "linux irq type". A mask for such bits exists,
IRQ_TYPE_SENSE_MASK, and as a matter of fact it is used in
irq_domain_xlate_twocell(), use it for irq_domain_xlate_onetwocell() as
well.
Fixes: 16b2e6e2f31d ("irq_domain: Create common xlate functions that device
drivers can use")
