[PATCH v2 1/2] drm/msm/adreno: warn if chip revn is verified before being set

[Stephen Boyd]

> The commit 010c8bbad2cb ("drm: msm: adreno: Disable preemption on Adreno
> 510") tried to check GPU's revn before revn being set. Add WARN_ON_ONCE
> to prevent such bugs from happening again. A separate helper is
> necessary so that the warning is displayed really just once instead of
> being displayed for each of comparisons.
