IS_REACHABLE(CONFIG_RC_CORE) code
It is a bit confusing how CEC_CAP_RC and IS_REACHABLE(CONFIG_RC_CORE)
interact. By stripping CEC_CAP_RC at the beginning rather than after #else
it should be a bit clearer what is going on.

Currently when the RC Core is enabled (reachable) core code located
in cec_register_adapter() attempts to populate the RC structure with
a pointer to the 'parent' passed in by the caller.
Unfortunately if the caller did not specify RC capability when calling
cec_allocate_adapter(), then there will be no RC structure to populate.
This causes a "NULL pointer dereference" error.

Also handle the corner case of "adapter is unconfigured AND the message

The CEC_TRANSMIT ioctl now returns -EPERM if an attempt is made to
transmit a message for an unconfigured adapter (i.e. userspace

This differentiates this case from when LAs are configured, but no
physical address is set. In that case -ENONET is returned.

The CEC specifications explicitly allows you to send poll messages and
Image/Text View On messages to a TV, even when unconfigured (i.e. there is
no hotplug signal detected). Some TVs will pull the HPD low when switching
to another input, or when going into standby, but CEC should still be
allowed to wake up such a display.
Add support for sending messages with initiator 0xf (Unregistered) and
destination 0 (TV) when no physical address is present.
This also required another change: the CEC adapter has to stay enabled as
long as 1) the CEC device is configured or 2) at least one filehandle is open
for the CEC device.

Interrupts with the IRQF_FORCE_RESUME flag set have also the
IRQF_NO_SUSPEND flag set. They are not disabled in the suspend path, but
must be forcefully resumed. That's used by XEN to keep IPIs enabled beyond
the suspension of device irqs. Force resume works by pretending that the
interrupt was disabled and then calling __irq_enable().
Incrementing the disabled depth counter was enough to do that, but with the
recent changes which use state flags to avoid unnecessary hardware access,
this is not longer sufficient. If the state flags are not set, then the
hardware callbacks are not invoked and the interrupt line stays disabled in
"hardware".
Set the disabled and masked state when pretending that an interrupt got
disabled by suspend.

Shared interrupts do not go well with disabling auto enable:
1) The sharing interrupt might request it while it's still disabled and
then wait for interrupts forever.
2) The interrupt might have been requested by the driver sharing the line
before IRQ_NOAUTOEN has been set. So the driver which expects that
disabled state after calling request_irq() will not get what it wants.
Even worse, when it calls enable_irq() later, it will trigger the
unbalanced enable_irq() warning.

If an interrupt is marked NOAUTOEN then request_irq() installs the action,
but does not enable the interrupt via startup_irq(). The interrupt is
enabled via enable_irq() later from the driver. enable_irq() calls
irq_enable().
That means that for interrupts which have a irq_startup() callback this
callback is never invoked. Neither is irq_domain_activate_irq() invoked for
such interrupts.
If an interrupt depends on irq_startup() or irq_domain_activate_irq() then
the enable via irq_enable() is not enough.
Add a status flag IRQD_IRQ_STARTED_UP and use this to select the proper
mechanism in enable_irq(). Use the flag also to avoid pointless calls into
the low level functions.

each gpio or pinctrl driver, and base defined in the gpio.h.
If the definition of base is 0, then it is the same as the
original, now the definition of base is 1000.
The dynamic assignment of a range of valid GPIOs should be

Per listen(fd, backlog) rules, there is really no point accepting a SYN,
sending a SYNACK, and dropping the following ACK packet if accept queue
is full, because application is not draining accept queue fast enough.
This behavior is fooling TCP clients that believe they established a
flow, while there is nothing at server side. They might then send about
10 MSS (if using IW10) that will be dropped anyway while server is under
stress.
