The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

Replace SET_SYSTEM_SLEEP_PM_OPS with its modern SYSTEM_SLEEP_PM_OPS()
alternative.
The combined usage of pm_ptr() and SYSTEM_SLEEP_PM_OPS()
allows the compiler to evaluate if the runtime suspend/resume() functions
are used at build time or are simply dead code.
This allows removing the __maybe_unused notation from the runtime
suspend/resume() functions.

CEC interrupt status/mask and logical address registers
will be reset when device enter suspend.
It will cause cec fail to work after device resume.
Add CEC suspend/resume functions, reinitialize logical address registers
and restore interrupt status/mask registers after resume.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

devm_add_action_or_reset()
The helper function devm_add_action_or_reset() will internally
call devm_add_action(), and if devm_add_action() fails then it will
execute the action mentioned and return the error code. So
use devm_add_action_or_reset() instead of devm_add_action()
to simplify the error handling, reduce the code.

It is possible for one HDMI connector to have multiple CEC adapters. The
typical real-world scenario is that where one adapter is used when the
device is in standby, and one that's better/smarter when the device is
powered up.
The cec-notifier changes were made with that in mind, but I missed that in
order to support this you need to tell cec_notifier_cec_adap_unregister()
which adapter you are unregistering from the notifier.
Add this additional argument. It is currently unused, but once all drivers
use this, the CEC core will be adapted for these use-cases.

Use the new cec_notifier_cec_adap_(un)register() functions to
(un)register the notifier for the CEC adapter.
Also adds CEC_CAP_CONNECTOR_INFO capability to the adapter.
Changes since v3:
- add CEC_CAP_CONNECTOR_INFO to cec_allocate_adapter,
- replace CEC_CAP_LOG_ADDRS | CEC_CAP_TRANSMIT |
CEC_CAP_RC | CEC_CAP_PASSTHROUGH with CEC_CAP_DEFAULTS.
