CVE-2026-23295

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.
