Use tty kref to release the fake tty in usb_console_setup to avoid use
after free if the underlying serial driver has acquired a reference.
Note that using the tty destructor release_one_tty requires some more
state to be initialised.

The USB console currently allocates a temporary fake tty which is used
to pass terminal settings to the underlying serial driver.
The tty struct is not fully initialised, something which can lead to a
lockdep warning (or worse) if a serial driver tries to acquire a
line-discipline reference:
While accessing a scsi_device, the use count of the underlying LLDD module
is incremented. The module reference is retrieved through .module field of
struct scsi_host_template.
This mapping between scsi_device and underlying LLDD module works well

While accessing a unusual usb storage (ums-alauda, ums-cypress, ...),
the module reference count is not incremented. Because these drivers
allocate scsi hosts with usb_stor_host_template defined in usb-storage

This fixes it by adjusting module ref

Some controllers need to have external power supplied before toggling
the internal PORT_POWER bit.
Fixes: 11a7e5940514 (usb: ehci: add ehci_port_power interface) on i.MX51
where the controller would hang the machine when trying to enable PORT_POWER.

Hi Felipe,
I prepared this patchset in response to our discussion:
https://lkml.org/lkml/2014/12/29/193
It reverts of unproper patch and adds working solution of the problem
described in commit messages.
Best regards,
Robert Baldyga
Robert Baldyga (2):
Revert "usb: dwc2: gadget: kill requests
This patch fixes in simpler way the bug described in [1] and [2]. It
looks like DWC2 is the only UDC driver that doesn't force usb requests
to complete in ep_disable() function. This causes described problem,
because we have no guarantee that all requests will be completed before
unbind of usb func
This reverts commit 62f4f0651ce8ef966a0e5b6db6a7a524c268fdd2.
This patch is incomplete solution. It won't work without changes in udc-core,
which were considered as unacceptable (discussion [1]).
