The OPP core code doesn't check for the compatible string today and any faulty binding will go unnoticed.
Add a check in OPP core to take care of that.
Signed-off-by: Viresh Kumar viresh.kumar@linaro.org --- This patch replaces: "[PATCH 1/2] PM / OPP: compatible is an optional property".
FWIW, I have checked that none of the current users of operating-points-v2 had this problem and this patch can be merged safely.
