Recently, a WARN_ON() was introduced to ensure that revn is filled before
adreno_is_aXYZ is called. This however doesn't work very well when revn is
0 by design (such as for A635). Fill it in as a stopgap solution for
-fixes.

I'd have probably added:
Fixes: cc943f43ece7 ("drm/msm/adreno: warn if chip revn is verified
before being set")
or
Fixes: 192f4ee3e408 ("drm/msm/a6xx: Add support for Adreno 7c Gen 3 gpu")

I'd lean towards the former, given that this is a temporary workaround
until we do a more comprehensive overhaul and remove revn entirely
