As function ep_matches() is used to match endpoint with usb descriptor it's highly unintuitive that it modifies endpoint and descriptor structures fields. This patch moves code configuring ep and desc from ep_matches() to usb_ep_autoconfig_ss(), so now function ep_matches() does nothing more than its name suggests.

The same effect can be achieved by using capabilities flags, so now we can get rid of handling of hardware specific limitations in generic code. Signed-off-by:

Introduce endpoint matching mechanism basing on endpoint capabilities flags. We check if endpoint supports transfer type and direction requested in ep descriptor. Since we have this new endpoint matching mechanism there is no need to have old code guessing endpoint capabilities basing on its name, so we are getting rid of it. Remove also the obsolete comment.

Introduce struct usb_ep_caps which contains information about capabilities of usb endpoints - supported transfer types and directions. This structure should be filled by UDC driver for each of its endpoints, and will be used in epautoconf in new ep matching mechanism which will replace ugly guessing of endpoint capabilities basing on its name.

So far it was necessary for usb functions to set ep->driver_data in endpoint obtained from autoconfig to non-null value, to indicate that endpoint is claimed by function (in autoconfig it was checked if endpoint has set this field to non-null value, and if it has, it was assumed that it is claimed). It could cause bugs because if some function doesn't set this field autoconfig could return the same endpoint more than one time. To help to avoid such bugs this patch adds claimed flag to struct usb_ep, and encapsulates endpoint claiming mechanism inside usb_ep_autoconfig_ss() and usb_ep_autoconfig_reset(), so now usb functions don't need to perform any additional actions to mark endpoint obtained from autoconfig as claimed.

commit 913e4a90 ("usb: gadget: f_uac2: finalize wMaxPacketSize according to bandwidth") added a possible build warning when calling min(). In order to fix the warning, we just make sure to call min_t() and tell that its arguments should be u16. Cc: Peter Chen <peter.chen@freescale.com> Signed-off-by:
