CVE-2026-43446: accel/amdxdna: Fix runtime suspend deadlock when there is pending job
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 pmruntimeresumeandget(), it can deadlock with the runtime suspend path.
Fix this by moving pmruntimeresumeandget() 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.
