Description

In the Linux kernel, the following vulnerability has been resolved: drm/bridge: cdns-dsi: Replace deprecated UNIVERSAL_DEV_PM_OPS() The deprecated UNIVERSAL_DEV_PM_OPS() macro uses the provided callbacks for both runtime PM and system sleep. This causes the DSI clocks to be disabled twice: once during runtime suspend and again during system suspend, resulting in a WARN message from the clock framework when attempting to disable already-disabled clocks. [ 84.384540] clk:231:5 already disabled [ 84.388314] WARNING: CPU: 2 PID: 531 at /drivers/clk/clk.c:1181 clk_core_disable+0xa4/0xac ...

Bridge and panel drivers should only deal with runtime PM, as the DRM framework manages system-wide power transitions through the bridge enable() and disable() hooks.
