	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, after a soft
power-on reset using either the rmobile-reset driver, or the RESETA_N
button on the ape6evm board.  I could not trigger it on r8a7791.
I haven't tested this on any other r8a779x, or on r8a7779.

This was tested on r8a73a4/ape6evm (fixes the crash) and
r8a7791/koelsch (crash never seen).

Thanks for applying!
