This series updates DRM drivers to use new CEC notifier API.
Changes since v6:
Made CEC notifiers' registration and de-registration symmetric
in tda998x and dw-hdmi drivers. Also, accidentally dropped one
patch in v6 (change to drm_dp_cec), brought it back now.
Changes since v5:
Fixed a warning about a missing comment for a new member of
drm_dp_aux_cec struct. Sending to a wider audience,
including maintainers of respective drivers.
Changes since v4:
Addressing review comments.
Changes since v3:
Updated adapter flags in dw-hdmi-cec.
Changes since v2:
Include all DRM patches from "cec: improve notifier support,
add connector info connector info" series.
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.
