Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/bridge: cdns-dsi: Replace deprecated UNIVERSAL_DEV_PM_OPS()<br />
<br />
The deprecated UNIVERSAL_DEV_PM_OPS() macro uses the provided callbacks<br />
for both runtime PM and system sleep. This causes the DSI clocks to be<br />
disabled twice: once during runtime suspend and again during system<br />
suspend, resulting in a WARN message from the clock framework when<br />
attempting to disable already-disabled clocks.<br />
<br />
[ 84.384540] clk:231:5 already disabled<br />

<br />
To address this issue, replace UNIVERSAL_DEV_PM_OPS() with<br />
RUNTIME_PM_OPS(). Bridge and panel drivers should only deal with runtime<br />
PM, as the DRM framework manages system-wide power transitions through<br />
the bridge enable() and disable() hooks.
