Hi,
This series fixes an intermittent crash (NULL pointer dereference) in
the rcar-thermal driver due to a race condition, and restores symmetry
in the error and remove paths.
So far I could trigger the race condition only on r8a73a4, and only
after a soft power-on reset using the rmobile-reset driver, which is
queued for v3.20. I could not trigger it on r8a7791.
I haven't tested this on any other r8a779x, or on r8a7779.
Hence I'm not sure it's worthwhile adding this to -stable yet.
This was tested on r8a73a4/ape6evm (fixes the crash) and
r8a7791/koelsch (crash not seen).
Thanks!
