Official description

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix dead lock for suspend and resume When an application issues a query IOCTL while auto suspend is running, a deadlock can occur. The query path holds dev_lock and then calls pm_runtime_resume_and_get(), which waits for the ongoing suspend to complete. Meanwhile, the suspend callback attempts to acquire dev_lock and blocks, resulting in a deadlock. Fix this by releasing dev_lock before calling pm_runtime_resume_and_get() and reacquiring it after the call completes. Also acquire dev_lock in the resume callback to keep the locking consistent.
