a610d60e88 drivers/misc/hdcp: add error handling for failed app initialization 
Add error handling code for use cases in which HDCP app initialization
fails and the QSEECOM handle is invalid. This ensures that the HDCP
QSEECOM library can handle these scenarios gracefully.

9df5c68339 drm/msm: modularize QSEECOM and HDCP functionalities 
Create separate modules to handle QSEECOM communications with the
TrustZone layer and to manage the HDCP 2.2 state machine.
This modularization will improve the extensibility and testability
of each module.

c33016dbc6 drivers/misc: create new module to handle sysfs and topology events 
Create a new module to handle sysfs and topology events that are
related to application/userspace layer interactions for HDCP
functionality. In turn, this will create a clear separation from
the HDCP QSEECOM layer that defines the communication mechanism between
the kernel and the TrustZone layers.
