This reverts commit abb540b5397674243994c5327146b6fed7339b71 which is
commit b7bd98b7db9f upstream.  I had added it to make another patch
apply cleanly, but as Ben points out, that was wrong.

commit 299d7572e46f98534033a9e65973f13ad1ce9047 upstream.

Make sure to reset the USB-console port pointer when console setup fails
in order to avoid having the struct usb_serial be prematurely freed by
the console code when the device is later disconnected.

commit aec17e1e249567e82b26dafbb86de7d07fde8729 upstream.

KASAN enabled configuration reports an error

    BUG: KASAN: use-after-free in usb_composite_overwrite_options+...
                [libcomposite] at addr ...
    Read of size 1 by task ...

when some driver is un-bound and then bound again.
For example, this happens with FunctionFS driver when "ffs-test"
test application is run several times in a row.

If the driver has empty manufacturer ID string in initial static data,
it is then replaced with generated string. After driver unbinding
the generated string is freed, but the driver data still keep that
pointer. And if the driver is then bound again, that pointer
is re-used for string emptiness check.

The fix is to clean up the driver string data upon its unbinding
to drop the pointer to freed memory.

commit 29c7f3e68eec4ae94d85ad7b5dfdafdb8089f513 upstream.

The DREQE bit of the DnFIFOSEL should be set to 1 after the DE bit of
USB-DMAC on R-Car SoCs is set to 1 after the USB-DMAC received a
zero-length packet. Otherwise, a transfer completion interruption
of USB-DMAC doesn't happen. Even if the driver changes the sequence,
normal operations (transmit/receive without zero-length packet) will
not cause any side-effects. So, this patch fixes the sequence anyway.

commit 5a838a13c9b4e5dd188b7a6eaeb894e9358ead0c upstream.

xhci driver keeps a bus_state structure for each hcd (usb2 and usb3)

The structure is picked based on hcd speed, but driver only compared
for HCD_USB3 speed, returning the wrong bus_state for HCD_USB31 hosts.

This caused null pointer dereference errors in bus_resume function.

commit bd7a3fe770ebd8391d1c7d072ff88e9e76d063eb upstream.

Andrey Konovalov reported a possible out-of-bounds problem for a USB interface
association descriptor.  He writes:
	It seems there's no proper size check of a USB_DT_INTERFACE_ASSOCIATION
	descriptor. It's only checked that the size is &gt;= 2 in
	usb_parse_configuration(), so find_iad() might do out-of-bounds access
	to intf_assoc-&gt;bInterfaceCount.

And he's right, we don't check for crazy descriptors of this type very well, so
resolve this problem.  Yet another issue found by syzkaller...

commit b2a542bbb3081dbd64acc8929c140d196664c406 upstream.

Commit e0429362ab15
("usb: Add device quirk for Logitech HD Pro Webcams C920 and C930e")
introduced quirk to workaround an issue with some Logitech webcams.

The workaround is introducing delay for some USB operations.

According to our testing, delay introduced by original commit
is not long enough and in rare cases we still see issues described
by the aforementioned commit.

This patch increases delays introduced by original commit.
Having this patch applied we do not see those problems anymore.
