Hi Guenter,

this patch enforces the state where the dedicated regulator is disabled,
no matter what the history of the regulator was. If a previous
regulator_disable() failed, it would still be desirable that the
regulator gets disabled the next time the driver is probed (i.e. a new
attempt to disable it on failure).
cc2_disable() checks first if the regulator is enabled to avoid any
imbalance.

Best regards,
Javier Carrasco
