It seems better to pass around a struct pointer in place of all those
separate out arguments, e.g. struct const_upload_info. Then you can
name the helper get_"structname"() too.

Preexisting, but "n" is a bit confusing, especially considering that
there is a "count" too. Something like "available_major" /
"reg_count"? count might be "component_count" or similar. Maybe you
can find some better names...
