udc_start() should only trigger the internal state machine and make

callback and after the callback the pullup().
udc_stop() is simillar, udc-core calls pullup(), unbind() and finally
udc_stop().

SuperSpeed USB has defined a new descriptor, called
the Binary Device Object Store (BOS) Descriptor. It
has also changed a bit the definition of SET_FEATURE
and GET_STATUS requests to add USB3-specific details.
This patch implements both changes to the Composite
Gadget Framework.

This patch defines necessary fields to support
streaming for USB3.0.
It implements a new function, called
usb_ep_autoconfig_ss(), to be used instead of the
existing usb_ep_autoconfig() when working in
SuperSpeed mode and there is a need to search for
an endpoint according to the number of required
streams.

f_rmnet.c,f_rmnet_sdio,f_rmnet_smd,f_rmnet_smd_sdio,f_serial.f_ccid.c.
Also merged a patch in f_serial.c for correct checking of the return value
of config_ep_by_speed. See "usb: gadget: fix g_serial regression".
Also fix a bug in ci13xxx_udc. Since f_serial is now checking if the endpoint
descriptors are null in the set_alt function, need to set them to null on
ep_disable in case of cable disconnect. Since the ep descriptor was inserted
to struct usb_ep in "usb: gadget: add usb_endpoint_descriptor to struct usb_ep"
then simply convert the ci13xxx_udc to work with mEp->ep.desc instead of
mEp->desc, this will ensure that the correct descriptor will be cleared
on endpoint disable.
I will upstream it to Linux community soon, I will name it:
"usb: gadget: use usb ep descriptor of struct usb_ep instead of wrapper desc"]

Change usb_ep_enable() prototype to use endpoint
descriptor from usb_ep.
This optimization spares the FDs from saving the
endpoint chosen descriptor. This optimization is
not full though. To fully exploit this change, one
needs to update all the UDCs as well since in the
current implementation each of them saves the
endpoint descriptor in it's internal (and extended)
endpoint structure.

this class will be used to abstract away several of the duplicated
operations scattered among the USB gadget controller drivers.
Later, we can add an atomic notifier to tell interested drivers about
what's happening with the controller. Notifications such as suspend,
resume, enumerated, etc. will be useful, at a minimum, for implementing
usb charger detection.
As part of the converting process usb_gadget_probe_driver() is no longer
part of each udc but pushed into the ->stap() callback. The same for his
couterpart.
The core is currently set explicit to 'n'. It will be changed to 'y' once
all users are converted since it provides functions which clash with
other drivers.

Add the ability to selectively enable over current protection
(OCP) for LVS and MVS type PMIC voltage switches. OCP is used to
automatically disable the output of a PMIC switch in hardware when
the load on the switch becomes too large.
The sequence used when enabling a switch when OCP is desired is as
follows:
1. Disable OCP.
2. Enable the switch.
3. Wait for ocp_enable_time microseconds.
4. Enable OCP.
This sequence is used to ensure that sufficient time is allowed
for inrush current to subside so that a false OCP event is not
triggered. The delay time is board specific.

[ Upstream commit 5ee4433efe99b9f39f6eff5052a177bbcfe72cea ]
By definition net_generic should never be called when it can return
NULL. Fail conspicously with a BUG_ON to make it clear when people mess
up that a NULL return should never happen.
Recently there was a bug in the CAIF subsystem where it was registered
with register_pernet_device instead of register_pernet_subsys. It was
erroneously concluded that net_generic could validly return NULL and
that net_assign_generic was buggy (when it was just inefficient).
Hopefully this BUG_ON will prevent people to coming to similar erroneous
conclusions in the futrue.

commit 598781d71119827b454fd75d46f84755bca6f0c6 upstream.
If the master tries to authenticate a client using drm_authmagic and
that client has already closed its drm file descriptor,
either wilfully or because it was terminated, the
call to drm_authmagic will dereference a stale pointer into kmalloc'ed memory
and corrupt it.
Typically this results in a hard system hang.
This patch fixes that problem by removing any authentication tokens
(struct drm_magic_entry) open for a file descriptor when that file
descriptor is closed.

Due to a limitation in how the video hardware is able
to access memory, fmem needs to be able to allocate a
physically contiguous block of memory that can be split into
two pieces. One piece will be managed by fmem
while the other piece (reserved) will not be handled by fmem.
The hardware limitation requires the reserved part to be at
a lower address than the other piece managed by fmem.
Add a new parameter to fmem that allows platform
data to specify the size of the piece that should not
be managed by fmem.
