Subject: gpio: 104-idi-48: Allow IRQ sharing
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4332e0144fe44cfc9a9c851f0edcab92ead2adbd;p=linux-beck.git

gpio: 104-idi-48: Allow IRQ sharing

The ACCES 104-IDI-48 can differentiate between its own and other
devices' interrupt requests. Therefore, IRQ sharing is possible and
should be permitted.
