Thanks Aaron,

I seem to be after tracing this I get to the line,

config->acquire_ctx = NULL;


in the function ,drm_modeset_unlock_all after we follow thorough on
the if statement for
ret in the function, drm_universal_plane_init as this causes an error
in the function for
what I get from reading the code. Seems the function ,
drm_modset_unlock seems to
be rewritten in order to avoid this.
Regards Nick
