In the Linux kernel, the following vulnerability has been resolved:

clk: qcom: dispcc-eliza: Fix disp_cc_mdss_mdp_clk_src RCG stall on Eliza EVK

Eliza EVK (eliza-cqs-evk.dts) does not have display enabled, however its Display Clock Controller is enabled and references parent clocks from DSI PHYs, which causes clock reparenting issues during probe (init) and warning on Eliza EVK:
