Probably best to add a CONFIG_DM_USB_GADGET conditional there. That seems to be the problem there. I just thought that nobody would care about non-CONFIG_DM_USB_GADGET and overlooked the omap3 configs. Regards, Andreas
Hi, just noticed I am doing two things in one patch. better do it with just some patches On Mon, 12 Dec 2022 14:00:57 -0500 Tom Rini <trini@konsulko.com> wrote: > On Sat, Nov 26, 2022 at 11:30:10PM +0100, Andreas Kemnade wrote: > > > Host mode structures were accessed but not initialized first thing -> struct usb_bus_priv *priv = dev_get_uclass_priv(dev); which will be zero if not in host mode (and later priv->something is accessed unconditional. > > and gadget dm did not compile at all. > > preparing things for DM_USB_GADGET should probably better a separate patch.
