Instead of unconditionally writing SOLO_EOSD_EXT_SIZE() bytes to the OSD
area (which is 64 or 128 kB depending on the PCI board) we only
write the actual amount of data needed which is 16 * OSD_TEXT_MAX (= 16 * 44).

The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.
The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.
The pwc amd sdr-msi3101 drivers both had this construction:
if (mutex_lock_interruptible(&s->v4l2_lock))
return -ERESTARTSYS;
This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

dynamically. There's also a raft of gadget driver updates and fixes,
CONFIG_USB_DEBUG is finally gone now that everything has been

drivers were cleaned up and the config option removed. There were
also other minor things all through the drivers/usb/ tree, the

The sn9c102 driver is deprecated. It was moved to staging in
anticipation of its removal in a future kernel version. However, USB
devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when
both sn9c102 and gspca_sonixb are enabled.
We must migrate all the users of these devices to the gspca_sonixb
driver now, so that it gets sufficient testing before the sn9c102
driver is finally phased out.

"vb2: only call start_streaming if sufficient buffers are queued"
the vb2 framework warns on (WARN_ON()) if all the active buffers
are not released when streaming is stopped, initially the vb2 silently
released the buffer internally if the buffer was not released by
the driver.
This patch fixes following issue:

Potentially overflowing expression "(f_rf + f_if + f_if1) * lo_div"
with type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit
arithmetic before being used in a context which expects an expression
of type "u64" (64 bits, unsigned). To avoid overflow, cast either
operand to "u64" before performing the multiplication.

[ NOTE! This merge effective drops commit 4329b93b283c ("of: Reduce
indentation in of_graph_get_next_endpoint").
The of_graph_get_next_endpoint() function was moved and renamed by
commit fd9fdb78a9bf ("[media] of: move graph helpers from
drivers/media/v4l2-core to drivers/of"). It was originally called
v4l2_of_get_next_endpoint() and lived in the file
drivers/media/v4l2-core/v4l2-of.c.
In that original location, it was then fixed to support empty port
nodes by commit b9db140c1e46 ("[media] v4l: of: Support empty port
nodes"), and that commit clashes badly with the dropped "Reduce
intendation" commit. I had to choose one or the other, and decided
that the "Support empty port nodes" commit was more important ]

Implement SDR driver for Realtek RTL2832U chip as a DVB extension
module. SDR module is attached by DVB USB RTL28XXU driver as a DVB
SEC (satellite equipment controller) module. Abusing unused SEC here
has no harm as that is DVB-T only frontend.
SDR functionality is provided by RTL2832 DVB-T demodulator. I suspect
it is originally planned for DAB and FM, but it could be abused general
SDR, due to modern silicon tuners that has wide frequency range and a
lot of configurable parameters (filters, gains, ...).

In commit 02f142ecd24aaf891324ffba8527284c1731b561 support was added to
start_streaming to return -ENOBUFS if insufficient buffers were queued
for the DMA engine to start. The vb2 core would attempt calling
start_streaming again if another buffer would be queued up.
Later analysis uncovered problems with the queue management if start_streaming
would return an error: the buffers are enqueued to the driver before the
start_streaming op is called, so after an error they are never returned to
the vb2 core. The solution for this is to let the driver return them to
the vb2 core in case of an error while starting the DMA engine. However,
in the case of -ENOBUFS that would be weird: it is not a real error, it
just says that more buffers are needed. Requiring start_streaming to give
them back only to have them requeued again the next time the application
calls QBUF is inefficient.
This patch changes this mechanism: it adds a 'min_buffers_needed' field
to vb2_queue that drivers can set with the minimum number of buffers
required to start the DMA engine. The start_streaming op is only called
if enough buffers are queued. The -ENOBUFS handling has been dropped in
favor of this new method.
Drivers are expected to return buffers back to vb2 core with state QUEUED
if start_streaming would return an error. The vb2 core checks for this
and produces a warning if that didn't happen and it will forcefully
reclaim such buffers to ensure that the internal vb2 core state remains
consistent and all buffer-related resources have been correctly freed
and all op calls have been balanced.
__reqbufs() has been updated to check that at least min_buffers_needed
buffers could be allocated. If fewer buffers were allocated then __reqbufs
will free what was allocated and return -ENOMEM. Based on a suggestion from
Pawel Osciak.
__create_bufs() doesn't do that check, since the use of __create_bufs
assumes some advance scenario where the user might want more control.
Instead streamon will check if enough buffers were allocated to prevent
streaming with fewer than the minimum required number of buffers.
