From: Imre Deak <imre.d...@intel.com>
commit 2af5268180410b874fc06be91a1b2fbb22b1be0c upstream.
For an enabled DSC during HW readout the corresponding power reference
is taken along the CRTC power domain references in
get_crtc_power_domains(). Remove the incorrect get ref from the DSI
encoder hook.
Fixes: 2b68392e638d ("drm/i915/dsi: add support for DSC")
