| Subject: drm/msm/mdp5: rate limit pp done timeout warnings |
| |
| From: Brian Masney <masneyb@onstation.org> |
| |
| [ Upstream commit ef8c9809acb0805c991bba8bdd4749fc46d44a98 ] |
| |
| Add rate limiting of the 'pp done time out' warnings since these |
| warnings can quickly fill the dmesg buffer. |
