[PATCH 6.1 100/149] drm/rockchip: Dont spam logs in atomic check

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: Daniel Stone <daniels@xxxxxxxxxxxxx>

commit 43dae319b50fac075ad864f84501c703ef20eb2b upstream.

Userspace should not be able to trigger DRM_ERROR messages to spam the
logs; especially not through atomic commit parameters which are
completely legitimate for userspace to attempt.
