You can use err here instead. With that fixed,

This patch adds the bindings for the MSM DisplayPort HDCP registers
which are required to write the HDCP key into the display controller as
well as the registers to enable HDCP authentication/key
exchange/encryption.

From: Sean Paul
This patch updates the connector's property value in 2 cases which were
previously missed:
1- Content type changes. The value should revert back to DESIRED from
ENABLED in case the driver must re-authenticate the link due to the
new content type.
2- Userspace sets value
From: Sean Paul
Instead of forcing a modeset in the hdcp atomic check, simply return
true if the content protection value is changing and let the driver
decide whether a modeset is required or not.

Hello again,
This is the second version of the HDCP helper patchset. See version 1
here: https://patchwork.freedesktop.org/series/94623/
In this second version, I've fixed up the oopsies exposed by 0-day and
yamllint and incorporated early review feedback from the dt/dts reviews
