This RFC proposes a solution to keep protecting the fpga bridge against
the unloading of the low-level control modules while addressing the
limitations of the current implementation. Currently, the code assumes
that the low-level module registers a driver for the parent device that
is later used to take the module's refcount. This proposal removes this
limitation by adding a module owner field to the fpga_bridge struct that
can be set while registering the bridge.
The RFC patch is based on top of ("fpga: remove redundant checks for
bridge ops").
