Subject: [PATCH 5/5] i2c: core: Tidy up handling of init_irq
Date: Tue, 21 May 2019 16:05:02 +0100	[thread overview]
Message-ID: <20190521150502.27305-6-ckeepax@opensource.cirrus.com> (raw)
In-Reply-To: <20190521150502.27305-1-ckeepax@opensource.cirrus.com>

Only set init_irq during i2c_device_new and only handle client->irq on
the probe/remove paths.

Suggested-by: Benjamin Tissoires <benjamin.tissoires@redhat.com>
