Clean up query: greybus/audio_manager_module.c

[Deepak R Varma]

Hello,
I am reviewing the file: drivers/staging/greybus/audio_manager_module.c
and have found that there are several gb_audio_module_*_show functions
that accept "struct gb_audio_manager_module_attribute * " as a function
parameter. However, this parameter is not used and should not be
necessary. Would you suggest cleaning up such functions.

Thank you.
Deepak.
