CVE-2025-71303

In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Fix race condition when checking rpm_on

When autosuspend is triggered, driver rpm_on flag is set to indicate that

a suspend/resume is already in progress. However, when a userspace

application submits a command during this narrow window,

amdxdna_pm_resume_get() may incorrectly skip the resume operation because

the rpm_on flag is still set. This results in commands being submitted

while the device has not actually resumed, causing unexpected behavior.

The set_dpm() is called by suspend/resume, it relied on rpm_on flag to

avoid calling into rpm suspend/resume recursivly. So to fix this, remove

the use of the rpm_on flag entirely. Instead, introduce aie2_pm_set_dpm()

which explicitly resumes the device before invoking set_dpm(). With this

change, set_dpm() is called directly inside the suspend or resume execution

path. Otherwise, aie2_pm_set_dpm() is called.
