Subject: [PATCH 2/2] usb: gadget: udc: atmel: convert to platform driver
Date:   Tue,  5 Jul 2022 15:19:51 +0200
Message-Id: <20220705131951.1388968-2-michael@walle.cc>

The driver won't probe on a LAN9668 because the pinctrl driver isn't
ready yet. Probe deferral is not supported because the init section
is already discarded. With fw_devlink enabled, the probe won't even
be called. Convert the driver to a proper platform driver.
