--- Comment #2 from Ramalingam C <ramalingam.c at intel.com> ---
This is the first time we have the kms_content_protection run on CI
effectively. And catching a bug at IGT.

As per the HDCP design at kernel if content protection property is left at
DESIRED, then on subsequent modesets HDCP authentication will be attempted by
kernel on its own.

In Our IGT when we set "content protection" to DESIRED and wait for ENABLED
state, on error case assert take us out of kms_content_protection, leaving the
"content protection" at DESIRED state.

To avoid HDCP authentication and related logs in sugsequent tests we need to
fix this.

And another point is even within kms_content_protection, we dont want dmesg
errors incase of failure in authentication. So we need to cleanup all errors
the authentication flow by converting them into debug/info logs.

Will work on these solutions immediatly. Thanks
