In asds configured with V4L2_ASYNC_MATCH_OF, the v4l2 subdev can be
part of a devicetree overlay, for example:
&media_bridge {
...
my_port: port@0 {
#address-cells = <1>;
#size-cells = <0>;
reg = <0>;
ep: endpoint@0 {
remote-endpoint = <&camera0>;
};
};
};
/ {
fragment@0 {
target = <&i2c0>;
__overlay__ {
my_cam {
compatible = "foo,bar";
port {
camera0: endpoint {
remote-endpoint = <&my_port>;
...
};
};
};
};
};
};
Each time the overlay is applied, its of_node pointer will be
different. We are not interested in matching the pointer, what we
want to match is that the path is the one we are expecting. Change to
use of_node_cmp() so that we continue matching after the overlay has
been removed and reapplied.

Drivers might try to access and run enable_source and disable_source
handlers when the driver that implements these handlers is clearing
the handlers during its unregister.
Fix the following race condition:
process 1 process 2
request video streaming unbind au0828
v4l2 checks if tuner is free
... ...
au0828_unregister_media_device()
... ...
(doesn't hold graph_mutex)
mdev->enable_source = NULL;
if (mdev && mdev->enable_source) mdev->disable_source = NULL;
mdev->enable_source()
(enable_source holds graph_mutex)
As shown above enable_source check is done without holding the graph_mutex.
If unbind happens to be in progress, au0828 could clear enable_source and
disable_source handlers leading to null pointer de-reference.
Fix it by protecting enable_source and disable_source set and clear and
protecting enable_source and disable_source handler access and the call
itself.
process 1 process 2
request video streaming unbind au0828
v4l2 checks if tuner is free
... ...
au0828_unregister_media_device()
... ...
(hold graph_mutex while clearing)
mdev->enable_source = NULL;
if (mdev) mdev->disable_source = NULL;
(hold graph_mutex to check and
call enable_source)
if (mdev->enable_source)
mdev->enable_source()
If graph_mutex is held to just heck for handler being null and needs to be
released before calling the handler, there will be another window for the
handlers to be cleared. Hence, enable_source and disable_source handlers
no longer hold the graph_mutex and expect callers to hold it to avoid
forcing them release the graph_mutex before calling the handlers.

Using sprintf() with a non-literal string makes some compiler complain
when building with -Wformat-security (eg. clang reports "format string
is not a string literal (potentially insecure)").
Here sprintf() format parameter is indirectly a literal string so there
is no security issue. Nevertheless adding a "%s" format string to
silent the warning helps to detect real bugs in the kernel.

I saw from ZyDAS ZD1301 sniffs it sets chip sleeping by using
REG_MISC_CTRL. That has very huge effect for power management, around
0.9W. Sleep is still disabled for all the old hardware just to avoid
possible regression as meaning of register bits are unknown.
I tested it also with some other devices and it seems to be working,
but I still consider it to be too risky to change it default.

This patch creates 4 static debugfs entries to dump:
- the device-related information ("st-hva/device")
- the list of registered encoders ("st-hva/encoders")
- the current values of the hva registers ("st-hva/regs")
- the information about the last closed instance ("st-hva/last")
It also creates dynamically a debugfs entry for each opened instance,
("st-hva/<instance identifier>") to dump:
- the information about the frame (format, resolution)
- the information about the stream (format, profile, level,
resolution)
- the control parameters (bitrate mode, framerate, GOP size...)
- the potential (system, encoding...) errors
- the performance information about the encoding (HW processing
duration, average bitrate, average framerate...)
Each time a running instance is closed, its context (including the
debug information) is saved to feed, on demand, the last closed
instance debugfs entry.
