Description

Nvidia kernel oot code is not very perfect about the usage case of lock, but it doesn't affect  display and gpu feature.

Detailed warning trace as below:

============================================
WARNING: possible recursive locking detected
6.12.40-yocto-standard #1 Tainted: G           O
--------------------------------------------
nvpmodel/1028 is trying to acquire lock:
ffff0000ae5ab2d8 (&mutex->mutex#2)\{+.+.}-\{3:3}, at: alter_usermode_mappings+0x68/0x220 [nvgpu]
 
but task is already holding lock:
ffff0000ae5a3a70 (&mutex->mutex#2)\{+.+.}-\{3:3}, at: gk20a_pm_finalize_poweron+0x8c/0x800 [nvgpu]
 
other info that might help us debug this:
Possible unsafe locking scenario:
 
       CPU0
       ----
  lock(&mutex->mutex#2);
  lock(&mutex->mutex#2);
 
*** DEADLOCK ***
 
May be due to missing lock nesting notation
