While the mdp5_plane_install_properties() function calls drm_plane_create_zpos_property() with an initial value of 1, mdp5_plane_reset() will force it to another value depending on the plane type.
Fix the discrepancy by setting the initial zpos value to the same value in the drm_plane_create_zpos_property() call.
Could you please squash two msm/mdp5 patches into a single patch, making it clear that the code is moved.
Also please add: Fixes: 7d36db0be3b9 ("drm/msm/mdp5: switch to standard zpos property")
