Subject: [PATCH v2 05/14] staging: typec: fusb302: Use client->irq as irq if set
Date: Tue, 15 Aug 2017 22:04:53 +0200	[thread overview]
Message-ID: <20170815200502.17339-6-hdegoede@redhat.com> (raw)
In-Reply-To: <20170815200502.17339-1-hdegoede@redhat.com>

The fusb302 is also used on x86 systems where the platform code sets
the irq in client->irq and there is no gpio named fcs,int_n.
