Thanks for the patch. A couple of things you could address in a v2:

1) 'Constify' is not a real English word, or maybe it's made its way
into an urban dictionary by now. Anyway, it's a common patch action
and you can read more about and improve the 'why' in your description.

Try: $ git log --pretty=oneline --abbrev-commit | grep Constify
and you'll find many patch examples. I think you'll find a crisper
'why' for your patch description.

Also, here's a former Outreachy Interns blog about the topic:
https://medium.com/@bhumikagoyal/linux-kernel-const-annotation-8db591148e58

2) Now that you know about the work 'Constify' please use it in your
commit message so that it doesn't cause line wrap (80 lines) when doing 
$ git log --pretty=oneline --abbrev-commit audio_manager_module.c

See the First Patch Tutorial Section: Following the Driver commit style
