Gadget driver should always use config_ep_by_speed() to initialize
usb_ep struct according to usb device's operating speed. Otherwise,
usb_ep struct may be wrong if usb devcie's operating speed is changed.
The key point in this patch is that we want to make sure the desc pointer
in usb_ep struct will be set to NULL when gadget is disconnected.
This will force it to call config_ep_by_speed() to correctly initialize
usb_ep struct based on the new operating speed when gadget is
re-connected later.

Replace all the occurrences of FIELD_SIZEOF() with sizeof_field() except
at places where these are defined. Later patches will remove the unused
definition of FIELD_SIZEOF().
This patch is generated using following script:
EXCLUDE_FILES="include/linux/stddef.h|include/linux/kernel.h"
git grep -l -e "\bFIELD_SIZEOF\b" | while read file;
do
if [[ "$file" =~ $EXCLUDE_FILES ]]; then
continue
fi
sed -i -e 's/\bFIELD_SIZEOF\b/sizeof_field/g' $file;

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
"As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need
support for time64_t.
In completely unrelated work, I spent time on cleaning up parts of
this file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the
rest of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which
is the scsi ioctl handlers. I have patches for those as well, but they
need more testing or possibly a rewrite"

A handful of drivers all have a trivial wrapper around their ioctl
handler, but don't call the compat_ptr() conversion function at the
moment. In practice this does not matter, since none of them are used
on the s390 architecture and for all other architectures, compat_ptr()
does not do anything, but using the new compat_ptr_ioctl()
helper makes it more correct in theory, and simplifies the code.
I checked that all ioctl handlers in these files are compatible
and take either pointer arguments or no argument.

The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.

USB: changes for v5.5
We have TI's glue layer for the Cadence USB3 controller going
upstream. Tegra's XUDC driver is also going upstream with this pull
request.
Apart from these two big features, we have a bunch of patches switching
over to devm_platform_ioremap_resource() in order to simplify code a
little; and a non-critical fix for DWC3 usage via kexec.

We meet several NULL pointer issues if configfs_composite_unbind
and composite_setup (or composite_disconnect) are running together.
These issues occur when do the function switch stress test, the
configfs_compsoite_unbind is called from user mode by
echo "" to /sys/../UDC entry, and meanwhile, the setup interrupt
or disconnect interrupt occurs by hardware. The composite_setup
will get the cdev from get_gadget_data, but configfs_composite_unbind
will set gadget data as NULL, so the NULL pointer issue occurs.
This concurrent is hard to reproduce by native kernel, but can be
reproduced by android kernel.
In this commit, we introduce one spinlock belongs to structure
gadget_info since we can't use the same spinlock in usb_composite_dev
due to exclusive running together between composite_setup and
configfs_composite_unbind. And one bit flag 'unbind' to indicate the
code is at unbind routine, this bit is needed due to we release the
lock at during configfs_composite_unbind sometimes, and composite_setup
may be run at that time.

Commit fea3409112a9 ("USB: add direction bit to urb->transfer_flags") has
added a usb_urb_dir_in() helper function that can be used to determine
the direction of the URB. With that patch USB_DIR_IN control requests with
wLength == 0 are considered out requests by real USB HCDs. This patch
changes dummy-hcd to use the usb_urb_dir_in() helper to match that
behavior.

When fuzzing the USB subsystem with syzkaller, we currently use 8 testing
processes within one VM. To isolate testing processes from one another it
is desirable to assign a dedicated USB bus to each of those, which means
we need at least 8 Dummy UDC/HCD devices.
This patch increases the maximum number of Dummy UDC/HCD devices to 32
(more than 8 in case we need more of them in the future).

In R-Car Gen3 USB 3.0 Function, if host is detached an interrupt
will be generated and Suspended state bit is set in interrupt status
register. Interrupt handler will call driver->suspend(composite_suspend)
if suspended state bit is set. composite_suspend will call
ffs_func_suspend which will post FUNCTIONFS_SUSPEND and will be consumed
by user space application via /dev/ep0.
To be able to detect the host detach, USB_INT_1_B2_SPND to cover the
Suspended bit of the B2_SPND_OUT[9] from the USB Status Register
(USB_STA) register and perform appropriate action in the
usb3_irq_epc_int_1 function.

Salvator-X CN11 port is not recognized and reverse role switch does

With this commit, disconnection will be recognized and reverse role
switch will happen by a user space application. If phone is connected
again it will enumerate properly and will become visible in the
