Subject: [PATCH v2 2/3] Staging: greybus: Use inline function for gb_audio_manager_module

Convert 'gb_audio_manager_module' from a macro to a static
inline function, to make the relevant types apparent in the
definition and to benefit from the type checking performed by
the compiler at call sites.
