Here are some tiny USB fixes for a number of reported issues for

Nothing huge here, just a small collection of xhci and other driver bugs
that syzbot has been finding in some drivers. There is also a usbip fix
and a fix for the usbip fix in here :)
All have been in linux-next with no reported issues.

Most Siano devices require an alignment for the response.
Changeset f3be52b0056a ("media: usb: siano: Fix general protection fault in smsusb")
changed the logic with gets such aligment, but it now produces a
sparce warning:
drivers/media/usb/siano/smsusb.c: In function 'smsusb_init_device':
drivers/media/usb/siano/smsusb.c:447:37: warning: 'in_maxp' may be used uninitialized in this function [-Wmaybe-uninitialized]
447 | dev->response_alignment = in_maxp - sizeof(struct sms_msg_hdr);
| ~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~
The sparse message itself is bogus, but a broken (or fake) USB
eeprom could produce a negative value for response_alignment.
So, change the code in order to check if the result is not
negative.

The syzkaller USB fuzzer found a general-protection-fault bug in the
smsusb part of the Siano DVB driver. The fault occurs during probe
because the driver assumes without checking that the device has both
IN and OUT endpoints and the IN endpoint is ep1.
By slightly rearranging the driver's initialization code, we can make
the appropriate checks early on and thus avoid the problem. If the
expected endpoints aren't present, the new code safely returns -ENODEV
from the probe routine.

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5b

On some architectures such as arm64, siano chip based TV-tuner
USB devices are not recognized correctly due to coherent memory
allocation failure with the following error:

[ 683.652978] smsusb: probe of 1-1:1.0 failed with error -12
This is caused by dma_alloc_coherent(NULL, ...) returning NULL in

via kmalloc() and let the USB core do the DMA mapping and free.

Reported as a Kaffeine bug:
https://bugs.kde.org/show_bug.cgi?id=375811
The USB control messages require DMA to work. We cannot pass
a stack-allocated buffer, as it is not warranted that the
stack would be into a DMA enabled area.
On Kernel 4.9, the default is to not accept DMA on stack anymore
on x86 architecture. On other architectures, this has been a
requirement since Kernel 2.2. So, after this patch, this driver
should likely work fine on all archs.

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.
The patch was generated via the script below, and manually
adjusted if needed.

The media device node is registered and so made visible to user-space
before entities are registered and links created which means that the
media graph obtained by user-space could be only partially enumerated
if that happens too early before all the graph has been created.
To avoid this race condition, split the media init and registration
in separate functions and only register the media device node when
all the pending subdevices have been registered, either explicitly
by the driver or asynchronously using v4l2_async_register_subdev().
The media_device_register() had a check for drivers not filling dev
and model fields but all drivers in mainline set them and not doing
it will be a driver bug so change the function return to void and
add a BUG_ON() for dev being NULL instead.
Also, add a media_device_cleanup() function that will destroy the
graph_mutex that is initialized in media_device_init().

Adding support for the media controller for a pure DVB device
