This will fix null pointer dereference that was caused by
the driver attempting to resume ports that were not yet
registered.

Before the commit fc274c1e9973 ("USB: gadget: Add a new bus for gadgets")
gadget driver.bus was unused. For whatever reason, many UDC drivers set
this field explicitly to NULL in udc_start(). With the newly added gadget
bus, doing this will crash the driver during the attach.

The problem was first reported, fixed and tested with OMAP UDC and g_ether.
Other drivers are changed based on code analysis only.

Currently connect/disconnect of USB cable calls afunc_bind and
eventually increments the bNumEndpoints. Performing multiple
plugin/plugout will increment bNumEndpoints incorrectly, and on
the next plug-in it leads to invalid configuration of descriptor
and hence enumeration fails.

Fix this by resetting the value of bNumEndpoints to 1 on every
afunc_bind call.

__ffs_ep0_queue_wait executes holding the spinlock of &ffs->ev.waitq.lock
and unlocks it after the assignments to usb_request are done.
However in the code if the request is already NULL we bail out returning
-EINVAL but never unlocked the spinlock.

Fix this by adding spin_unlock_irq &ffs->ev.waitq.lock before returning.

Pull USB / Thunderbolt fixes from Greg KH:
 "Here are a number of small USB and Thunderbolt driver fixes and new
  device id changes for 6.2-rc5. Included in here are:

   - thunderbolt bugfixes for reported problems

   - new usb-serial driver ids added

   - onboard_hub usb driver fixes for much-reported problems

   - xhci bugfixes

   - typec bugfixes

   - ehci-fsl driver module alias fix

   - iowarrior header size fix

   - usb gadget driver fixes

  All of these, except for the iowarrior fix, have been in linux-next
  with no reported issues. The iowarrior fix passed the 0-day testing
  and is a one digit change based on a reported problem in the driver
  (which was written to a spec, not the real device that is now
  available)"

Commit ca07e1c1e4a6 ("drivers:usb:fsl:Make fsl ehci drv an independent
driver module") changed DRV_NAME which was used for MODULE_ALIAS as well.
Starting from this the module alias didn't match the platform device
name created in fsl-mph-dr-of.c
Change DRV_NAME to match the driver name for host mode in fsl-mph-dr-of.
This is needed for module autoloading on ls1021a.

The dwc3 core support now links against the extcon subsystem,
so it cannot be built-in when extcon is a loadable module:

arm-linux-gnueabi-ld: drivers/usb/dwc3/core.o: in function `dwc3_get_extcon':
core.c:(.text+0x572): undefined reference to `extcon_get_edev_by_phandle'
arm-linux-gnueabi-ld: core.c:(.text+0x596): undefined reference to `extcon_get_extcon_dev'
arm-linux-gnueabi-ld: core.c:(.text+0x5ea): undefined reference to `extcon_find_edev_by_node'

There was already a Kconfig dependency in the dual-role support,
but this is now needed for the entire dwc3 driver.

It is still possible to build dwc3 without extcon, but this
prevents it from being set to built-in when extcon is a loadable
module.
