Subject: [PATCH AUTOSEL 3.18 13/26] USB: omap_udc: fix omap_udc_start() on 15xx machines
Date: Wed, 5 Dec 2018 04:54:17 -0500 [thread overview]
Message-ID: <20181205095430.8019-13-sashal@kernel.org> (raw)
In-Reply-To: <20181205095430.8019-1-sashal@kernel.org>
From: Aaro Koskinen <aaro.koskinen@iki.fi>
[ Upstream commit 6ca6695f576b8453fe68865e84d25946d63b10ad ]
On OMAP 15xx machines there are no transceivers, and omap_udc_start()
always fails as it forgot to adjust the default return value.
