Summary

Turn the FEEDMATRIX_DECLARE macro into a single inline function
(feed_matrix_apply()). There is no reason to have this as a macro, it
only complicated the code. An advantage of this patch is that, because
we no longer call the functions created by the macro through function
pointers (apply field of feed_matrix_info), we can call
feed_matrix_apply() directly in feed_matrix_feed().

Event Timeline

Same as D48032, you may want to call your function with literal format parameters, for performance reasons.

sys/dev/sound/pcm/feeder_matrix.c
443

Why can't this entire switch statement just be feed_matrix_apply(info, src, dst, j, info->fmt);?

There is related discussion in D48032

Mark fmt argument as const.

Clamp accum, not v, as in the original code.
