[PATCH net-next v2 5/9] net: sparx5: move calendar initialization to probe

[Daniel Machon]

Move the calendar initialization from sparx5_start() to probe() by
creating a new sparx5_calendar_init() wrapper function that calls both
sparx5_config_auto_calendar() and sparx5_config_dsm_calendar().
Calendar initialization does not require cleanup.

Also, make the individual calendar config functions static since they
are now only called from within sparx5_calendar.c.
