The patches in this series are independent of each other. Keep them in
one series just for easy review and tracking.

Patch 1/6 fixes a bug introduced recently. In my test, reading the
domain info at a bogus address returns all 'f'. So the psys domain is
always probed both before and after the broke commit and there should be
no visible impact.

Patch 2/6 fixes a WARNING since 6.11-rc1. But the underlying problem is
there since the proc thermal driver was introduced. Lastest code still
handles it but with an extra WARNING. So I'm not sure if this should be
considered as -stable material or not.

Patch 3 - 6 are general improvements and cleanups.

thanks,
rui
