This series updates remaining drivers in DRM to use new CEC notifier API.
Those complement the "cec: improve notifier support, add
connector info" patch series and also replace 2 following patches from
there:
- [PATCHv8 09/13] dw-hdmi: use cec_notifier_conn_(un)register
- [PATCHv9 12/13] tda998x: use cec_notifier_conn_(un)register
None of those changes were not tested on a real hardware.
Changes since v1:
Those patches delay creation of notifiers until respective
connectors are constructed. It seems that those patches, for a
couple of drivers, by adding the delay, introduce a race between
notifiers' creation and the IRQs handling threads - at least I
don't see anything obvious in there that would explicitly forbid
such races to occur. v2 adds a write barrier to make sure IRQ
threads see the notifier once it is created (replacing the
WRITE_ONCE I put in v1). The best thing to do here, I believe,
would be not to have any synchronization and make sure that an IRQ
only gets enabled after the notifier is created.
