media: pulse8-cec/rainshadow-cec: make adapter name unique
The CEC adapter name used by the pulse8-cec and rainshadow-cec USB device drivers
was a fixed string, but it should be unique if you connect multiple of these devices
to the same computer.
Use dev_name(&serio->dev) instead, which make it unique again.

media: cec-pin: add low-level pin hardware support
Add support for CEC hardware that relies on low-level pin polling or
GPIO interrupts.
One example is the Allwinner SoC. But any GPIO-based CEC implementation can
use this as well.
A GPIO implementation is very suitable as well for debugging: it can use
interrupts to detect state changes and report it. Userspace can then verify
if the bus traffic is correct. This also makes error injection possible.
The disadvantage is that it is hard to get the timings right since linux
isn't a hard realtime system.
In general on an idle system it works quite well, but under load the timer
will miss its mark every so often.
The debugfs file /sys/kernel/debug/cec/cecX/status gives some statistics
with respect to the timer overruns.
When the adapter is unconfigured and the low-level driver supports
interrupts, then the interrupt will be used to detect changes. This should
be quite accurate. But when the adapter is configured a hrtimer has to be
used.
The hrtimer implements a state machine where for each state the code will
read the bus or drive the bus and go on to the next state. It will re-arm
the timer with a delay based on the next state.

media: cec: rework the cec event handling
Event handling was always fairly simplistic since there were only
two events. With the addition of pin events this needed to be redesigned.
The state_change and lost_msgs events are now core events with the
guarantee that the last state is always available. The new pin events
are a queue of events (up to 64 for each event) and the oldest event
will be dropped if the application cannot keep up. Lost events are
marked with a new event flag.

So the platform device ID table is only used to fill the aliases in

random: suppress spammy warnings about unseeded randomness
Unfortunately, on some models of some architectures getting a fully
seeded CRNG is extremely difficult, and so this can result in dmesg
getting spammed for a surprisingly long time. This is really bad from
a security perspective, and so architecture maintainers really need to
do what they can to get the CRNG seeded sooner after the system is
booted. However, users can't do anything actionble to address this,
and spamming the kernel messages log will only just annoy people.
For developers who want to work on improving this situation,
CONFIG_WARN_UNSEEDED_RANDOM has been renamed to
CONFIG_WARN_ALL_UNSEEDED_RANDOM. By default the kernel will always
print the first use of unseeded randomness. This way, hopefully the
security obsessed will be happy that there is _some_ indication when
the kernel boots there may be a potential issue with that architecture
or subarchitecture. To see all uses of unseeded randomness,
developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM.
