Description

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

accel/amdxdna: Fix runtime suspend deadlock when there is pending job

The runtime suspend callback drains the running job workqueue before suspending the device. If a job is still executing and calls pm_runtime_resume_and_get(), it can deadlock with the runtime suspend path.

Fix this by moving pm_runtime_resume_and_get() from the job execution routine to the job submission routine, ensuring the device is resumed before the job is queued and avoiding the deadlock during runtime suspend.
