This series fixes a reset of state in duplicate state crtc funcs for VOP driver, a possible crash and ensure crtc reset helper is called in VOP2 driver. Patch 1 use kmemdup instead of kzalloc to duplicate the crtc state. Patch 2 change to use crtc and plane cleanup helpers directly. Patch 3 adds a crash guard for empty crtc state. Patch 4 adds a missing call to crtc reset helper. This is the next part of an ongoing effort to upstream HDMI 2.0 support used in LibreELEC for the past 3+ years.
