drm/bridge: cdns-dsi: Replace deprecated UNIVERSAL_DEV_PM_OPS()

Type: advisorySource: OSV1 source record

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 ... [ 84.579183] Call trace: [ 84.581624] clk_core_disable+0xa4/0xac [ 84.585457] clk_disable+0x30/0x4c [ 84.588857] cdns_dsi_suspend+0x20/0x58 [cdns_dsi] [ 84.593651] pm_generic_suspend+0x2c/0x44 [ 84.597661] ti_sci_pd_suspend+0xbc/0x15c [ 84.601670] dpm_run_callback+0x8c/0x14c [ 84.605588] __device_suspend+0x1a0/0x56c [ 84.609594] dpm_suspend+0x17c/0x21c [ 84.613165] dpm_suspend_start+0xa0/0xa8 [ 84.617083] suspend_devices_and_enter+0x12c/0x634 [ 84.621872] pm_suspend+0x1fc/0x368 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.
