[PATCH 4.19 087/142] USB: omap_udc: fix omap_udc_start() on 15xx machines

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

[ 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.
