Subject: [PATCH v2 3/5] USB: omap_udc: fix omap_udc_start() on 15xx machines
Date: Sun, 25 Nov 2018 00:17:06 +0200	[thread overview]
Message-ID: <20181124221708.31003-4-aaro.koskinen@iki.fi> (raw)
In-Reply-To: <20181124221708.31003-1-aaro.koskinen@iki.fi>

On OMAP 15xx machines there are no transceivers, and omap_udc_start()
always fails as it forgot to adjust the default return value.
