Subject: [v3,07/12] staging: typec: tcpci: register port before request irq
Date: Tue, 13 Mar 2018 17:34:33 +0800 [thread overview]
Message-ID: <1520933678-10535-8-git-send-email-jun.li@nxp.com> (raw)
With that we can clear any pending events and the port is registered
so driver can be ready to handle typec events once we request irq.
