2019-09-18reset: reset-scmi: add missing handle initialisationSudeep Holla
scmi_reset_data->handle needs to be initialised at probe, so that it can be later used to access scmi reset protocol APIs using the same. Since it was tested with a module that obtained handle elsewhere, it was missed easily. Add the missing scmi_reset_data->handle initialisation to fix the issue.
