dt-bindings: i2c: maxim,max96712: Require setting bus-type property
The MAX96712 can support both a CSI-2 C-PHY and D-PHY bus. The initial
staging driver however only supported D-PHY and the bus-type property
was left optional.
In preparation for adding C-PHY support to the staging driver make the
bus-type property mandatory as it is needed to select the correct PHY
mode. Without the bus-type property present, the driver falls-back to
D-PHY mode, so the change is functionally backward compatible with old
DTS files lacking the property.
The only in-tree DTS file (renesas/r8a779a0-falcon-csi-dsi.dtsi) that
lacked the property uses D-PHY and have been updated.

VFE outputs the lines padded to a length multiple of 16 bytes. As in the
current driver the value of the bpl_alignment is set to 8 bytes, the frames
captured in formats with the bytes-per-line value being not a multiple of

media: videodev2.h: Fix struct v4l2_input tuner index comment
VIDIOC_ENUMINPUT documentation describes the tuner field of
struct v4l2_input as index:
Documentation/userspace-api/media/v4l/vidioc-enuminput.rst
"
* - __u32
- ``tuner``
- Capture devices can have zero or more tuners (RF demodulators).
When the ``type`` is set to ``V4L2_INPUT_TYPE_TUNER`` this is an
RF connector and this field identifies the tuner. It corresponds
to struct :c:type:`v4l2_tuner` field ``index``. For
details on tuners see :ref:`tuner`.
"
Drivers I could find also use the 'tuner' field as an index, e.g.:
drivers/media/pci/bt8xx/bttv-driver.c bttv_enum_input()
drivers/media/usb/go7007/go7007-v4l2.c vidioc_enum_input()
However, the UAPI comment claims this field is 'enum v4l2_tuner_type':
include/uapi/linux/videodev2.h
This field being 'enum v4l2_tuner_type' is unlikely as it seems to be
never used that way in drivers, and documentation confirms it. It seem
this comment got in accidentally in the commit which this patch fixes.
Fix the UAPI comment to stop confusion.
This was pointed out by Dmitry while reviewing VIDIOC_ENUMINPUT

staging: media: tegra-video: move MIPI calibration calls from VI to CSI
The CSI module does not handle all the MIPI lane calibration procedure,
leaving a small part of it to the VI module. In doing this,
tegra_channel_enable_stream() (vi.c) manipulates the private data of the
upstream subdev casting it to struct 'tegra_csi_channel', which will be
wrong after introducing a VIP (parallel video input) channel.
This prevents adding support for the VIP module. It also breaks the
logical isolation between modules.
Since the lane calibration requirement does not exist in the parallel input
module, moving the calibration function to a per-module op is not
optimal. Instead move the calibration procedure in the CSI module, together
with the rest of the calibration procedures. After this change,
tegra_channel_enable_stream() just calls v4l2_subdev_call() to ask for a

The tegra_default_format in vi.c is specific to Tegra210 CSI.
In preparation for adding Tegra20 VIP support, move the default format to a
new field in the soc-specific `struct tegra_vi_soc`. Instead of an entire
format struct, only store a pointer to an item in the existing format
array.
No functional changes. The format pointed to is the same that used to be in
vi.c.

For avoiding the potential deadlock, rewrite to an open-coded loop

media: dvb-core: Fix use-after-free due to race at dvb_register_device()
dvb_register_device() dynamically allocates fops with kmemdup()
to set the fops->owner.
And these fops are registered in 'file->f_ops' using replace_fops()
in the dvb_device_open() process, and kfree()d in dvb_free_device().
However, it is not common to use dynamically allocated fops instead
of 'static const' fops as an argument of replace_fops(),
and UAF may occur.
These UAFs can occur on any dvb type using dvb_register_device(),
such as dvb_dvr, dvb_demux, dvb_frontend, dvb_net, etc.
So, instead of kfree() the fops dynamically allocated in
dvb_register_device() in dvb_free_device() called during the
.disconnect() process, kfree() it collectively in exit_dvbdev()
called when the dvbdev.c module is removed.

A race condition may occur between the .disconnect function, which
is called when the device is disconnected, and the dvb_device_open()

This results in several types of UAFs.
The root cause of this is that you use the dvb_device_open() function,
which does not implement a conditional statement
that checks 'dvbnet->exit'.
So, add 'remove_mutex` to protect 'dvbnet->exit' and use

media: ttusb-dec: fix memory leak in ttusb_dec_exit_dvb()
Since dvb_frontend_detach() is not called in ttusb_dec_exit_dvb(),
which is called when the device is disconnected, dvb_frontend_free()
is not finally called.
This causes a memory leak just by repeatedly plugging and
unplugging the device.
Fix this issue by adding dvb_frontend_detach() to ttusb_dec_exit_dvb().

media: dvb_ca_en50221: fix a size write bug
The function of "dvb_ca_en50221_write_data" at source/drivers/media
/dvb-core/dvb_ca_en50221.c is used for two cases.
The first case is for writing APDU data in the function of
"dvb_ca_en50221_io_write" at source/drivers/media/dvb-core/
dvb_ca_en50221.c.
The second case is for writing the host link buf size on the
Command Register in the function of "dvb_ca_en50221_link_init"
at source/drivers/media/dvb-core/dvb_ca_en50221.c.
In the second case, there exists a bug like following.
In the function of the "dvb_ca_en50221_link_init",
after a TV host calculates the host link buf_size,
the TV host writes the calculated host link buf_size on the
Size Register.
Accroding to the en50221 Spec (the page 60 of
https://dvb.org/wp-content/uploads/2020/02/En50221.V1.pdf),
before this writing operation, the "SW(CMDREG_SW)" flag in the
Command Register should be set. We can see this setting operation
in the function of the "dvb_ca_en50221_link_init" like below.
...
if ((ret = ca->pub->write_cam_control(ca->pub, slot,
CTRLIF_COMMAND, IRQEN | CMDREG_SW)) != 0)
return ret;
...
But, after that, the real writing operation is implemented using
the function of the "dvb_ca_en50221_write_data" in the function of
"dvb_ca_en50221_link_init", and the "dvb_ca_en50221_write_data"
includes the function of "ca->pub->write_cam_control",
and the function of the "ca->pub->write_cam_control" in the
function of the "dvb_ca_en50221_wrte_data" does not include
"CMDREG_SW" flag like below.
...
if ((status = ca->pub->write_cam_control(ca->pub, slot,
CTRLIF_COMMAND, IRQEN | CMDREG_HC)) != 0)
...
In the above source code, we can see only the "IRQEN | CMDREG_HC",
but we cannot see the "CMDREG_SW".
The "CMDREG_SW" flag which was set in the function of the
"dvb_ca_en50221_link_init" was rollbacked by the follwoing function
of the "dvb_ca_en50221_write_data".
This is a bug. and this bug causes that the calculated host link buf_size
is not properly written in the CI module.
Through this patch, we fix this bug.

media: netup_unidvb: fix irq init by register it at the end of probe
IRQ handler netup_spi_interrupt() takes spinlock spi->lock. The lock
is initialized in netup_spi_init(). However, irq handler is registered
before initializing the lock.
Spinlock dma->lock and i2c->lock suffer from the same problem.
Fix this by registering the irq at the end of probe.
