* [PATCH] usb: typec: Ensure USB_ROLE_SWITCH is a dependency for tps6598x

When I switched on USB role switching for the tps6598x I completely forgot
to add the Kconfig dependency.

This patch ensures the dependency is there to prevent compilation error
when role-switching is off.

There are stubs for the those functions, so there should not be any
compilation errors.

How about this:

	depends on USB_ROLE_SWITCH || !USB_ROLE_SWITCH

We then would have an option to use this driver even without that when
its not needed.

That's what I initially thought too, then I saw this.

git show da4b5d18dd949abdda7c8ea76c9483b5edd49616

but looking at role.h

#if IS_ENABLED(CONFIG_USB_ROLE_SWITCH)

int usb_role_switch_set_role(struct usb_role_switch *sw, enum usb_role 
role);

#else

static inline int usb_role_switch_set_role(struct usb_role_switch *sw,
                 enum usb_role role)
{
         return 0;
}

#endif

That should work.

Hmm, let me see if I can figure this out...

ah ha - look at what role switch is defaulting to

CONFIG_USB_ROLE_SWITCH=m

So anything linked into the kernel image will not resolve those symbols

So it should be "select USB_ROLE_SWITCH" not "depends on USB_ROLE_SWITCH"

No. The consumers of the switches should depend on it, not silently
select it.

Note that all those except tcpm supply the switch.
