This series constifies the attribute group groups arrays in a number
of structs, plus some preparation work. This allows to assign constant
arrays, w/o "discards const qualifier" compiler warning.
This is a step towards to goal to e.g. create constant arrays in macro
__ATTRIBUTE_GROUPS().

There may be drivers not covered by my test scenarios which conflict
with this series. Therefore I send it as RFC for now.
Hopefully some CI checking this series provides additional hints.

Heiner Kallweit (10):
  IB/core: Prepare for immutable device groups
  rtc: prepare for struct device member groups becoming a constant array
  sysfs: constify group arrays in function arguments
  driver: core: constify groups array argument in device_add_groups and
    device_remove_groups
  driver core: make struct device member groups a constant array
  driver core: make struct device_type member groups a constant array
  driver core: make struct bus_type groups members constant arrays
  driver core: make struct class groups members constant arrays
  driver core: make struct device_driver groups members contact arrays
  kobject: make struct kobject member default_groups a constant array
