Subject: [PATCH] gpio: 104-idi-48: Allow IRQ sharing
Date: Wed, 20 Jan 2016 13:57:31 -0500 [thread overview]
Message-ID: <20160120185731.GA10340@sophia> (raw)
The ACCES 104-IDI-48 can differentiate between its own and other
devices' interrupt requests. Therefore, IRQ sharing is possible and
should be permitted.
