 After losing an entire day with a cryptic message telling me my view:

 > didn't return an HttpResponse object. It returned an unawaited coroutine
 instead. You may need to add an 'await' into your view.

 Even though the function was a literal single line `return
 HttpResponse('a')`. On the next day I found out the problem was because I
 was using the `csrf_exempt` decorator.

 This patch 'fixes' that, allowing this decorator to be used by async
 functions as well.

 Couldn't find how to make an automated test for that so it's not included,
 someone else has to create it or guide me on where and how to do it.

 Flake8 didn't complain and there's no need for extra documentation as it
 just improves async support in more existing features.
