Merge branch 'ewma'
Johannes Berg says:
====================
average: convert users to inline implementation
Since there's very little benefit of the out-of-line implementation
(a single byte of .text in one driver as far as I've seen), convert
all drivers to the inline implementation, saving memory, and remove
the out-of-line implementation.
====================
