| 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

To address this issue, replace UNIVERSAL_DEV_PM_OPS() with
RUNTIME_PM_OPS(). 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. |
