From: Luca Coelho <[email protected]> Instead of accessing the iwl_config_trans_params from the cfg that is stored in the trans struct, pass this structure directly to functions that need it during trans_alloc. This will be useful to isolate the elements needed during allocation and pass them separately before the actual cfg struct is known.
