It allows to user, invoked platform device registration for "i2c-mux-mlxcpld" driver, to be notified that mux infrastructure is available, and thus some devices could be connected to this infrastructure.

i2c: mux: mlxcpld: Get rid of adapter numbers enforcement 2021-02-09T10:35:28+00:00 Vadim Pasternak vadimp@nvidia.com 2021-02-08T20:16:03+00:00 cae5216387d18c888f9f38a0cf5be341a0af75a6 Do not set the argument 'force_nr' of i2c_mux_add_adapter() routine, instead provide argument 'chan_id'. Rename mux ids array from 'adap_ids' to 'chan_ids'. The motivation is to prepare infrastructure to be able to: - Create only the child adapters which are actually needed - for which channel ids are specified. - To assign 'nrs' to these child adapters dynamically, with no 'nr' enforcement.
