entry in the notifier's list, be that either waiting or done lists, while
the notifier's asc_list is removed.

media: v4l: async: Rename v4l2_async_subdev as v4l2_async_connection
Rename v4l2_async_subdev as v4l2_async_connection, in order to
differentiate between the sub-devices and their connections: one
sub-device can have many connections but the V4L2 async framework has so
far allowed just a single one. Connections in this context will later
translate into either MC ancillary or data links.
This patch prepares changing that relation by changing existing users of
v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices
themselves will not be needed anymore
Additionally, __v4l2_async_nf_add_subdev() has been renamed
__v4l2_async_nf_add_connection().
V4L2 async sub-device matching originally used the device nodes only.
Endpoint nodes were taken into use instead as using the device nodes was
problematic for it was in some cases ambiguous which link might have been
in question.
There is however no need to use endpoint nodes on both sides, as the async
sub-device's fwnode can always be trivially obtained using
fwnode_graph_get_remote_endpoint() when needed while what counts is
whether or not the link is between two device nodes, i.e. the device nodes
match.
This will briefly break the adv748x driver but it will be fixed later in
the set, by patch "media: adv748x: Return to endpoint matching".

Commit fe8a33978383 ("media: mediatek: vcodec: Read HW active status

syscon instead of from the reg property when reg-names are supplied.
However as part of that change, a smatch warning was introduced:
With a correct Devicetree, that is, one that follows the dt-binding, it
wouldn't be possible to trigger such a buffer overflow. Even so, update
the range validation of the reg property, so that the smatch warning is
fixed and if an incorrect Devicetree is ever supplied the code errors
out instead of causing memory corruption.

Each iteration initializes one element in the msg_queue->lat_buf[] array
and then the clean up function vdec_msg_queue_deinit() frees each
element of the msg_queue->lat_buf[] array. This clean up code relies
on the assumption that every element is either initialized or zeroed.

media: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

media: dvb-usb-v2: gl861: Fix null-ptr-deref in gl861_i2c_master_xfer
In gl861_i2c_master_xfer, msg is controlled by user. When msg[i].buf
is null and msg[i].len is zero, former checks on msg[i].buf would be
passed. Malicious data finally reach gl861_i2c_master_xfer. If accessing
msg[i].buf[0] without sanity check, null ptr deref would happen.
We add check on msg[i].len to prevent crash.

If opera1_xilinx_rw fails, the mac address is not initialized.
And opera1_read_mac_address does not handle this failure, which leads to
the uninit-value in dvb_usb_adapter_dvb_init.
Fix this by handling the failure of opera1_xilinx_rw.

The previous commit 4b208f8b561f ("[media] siano: register media controller
earlier")moves siano_media_device_register before smscore_register_device,
and adds corresponding error handling code if smscore_register_device
fails. However, it misses the following error handling code of
smsusb_init_device.
Fix this by moving error handling code at the end of smsusb_init_device
and adding a goto statement in the following error handling parts.
