[PATCH v2 0/2] thermal: rcar: Fix crash and restore symmetry
From: Geert Uytterhoeven
Date: Mon Feb 23 2015 - 10:38:00 EST
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!
