mfd: rk808: Check pm_power_off pointer
The function pointer pm_power_off may point to function from other module (PSCI for example). If rk808 is removed, pm_power_off is overwritten to NULL and the system cannot be powered off. This patch checks if pm_power_off points to a module function. Signed-off-by: Stefan Mavrodiev <stefan@olimex.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
