      "title": "drm/msm/dpu: fix mismatch between power and frequency",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/msm/dpu: fix mismatch between power and frequency\n\nDuring DPU runtime suspend, calling dev_pm_opp_set_rate(dev, 0) drops\nthe MMCX rail to MIN_SVS while the core clock frequency remains at its\noriginal (highest) rate. When runtime resume re-enables the clock, this\nmay result in a mismatch between the rail voltage and the clock rate.\n\nFor example, in the DPU bind path, the sequence could be:\n  cpu0: dev_sync_state -> rpmhpd_sync_state\n  cpu1:                                     dpu_kms_hw_init\ntimeline 0 ------------------------------------------------> t\n\nAfter rpmhpd_sync_state, the voltage performance is no longer guaranteed\nto stay at the highest level. During dpu_kms_hw_init, calling\ndev_pm_opp_set_rate(dev, 0) drops the voltage, causing the MMCX rail to\nfall to MIN_SVS while the core clock is still at its maximum frequency.\nWhen the power is re-enabled, only the clock is enabled, leading to a\nsituation where the MMCX rail is at MIN_SVS but the core clock is at its\nhighest rate. In this state, the rail cannot sustain the clock rate,\nwhich may cause instability or system crash.\n\nRemove the call to dev_pm_opp_set_rate(dev, 0) from dpu_runtime_suspend\nto ensure the correct vote is restored when DPU resumes.\n\nPatchwork: https://patchwork.freedesktop.org/patch/710077/",
