[alsa-devel] [PATCH 5.6 36/71] ALSA: emu10k1: Use managed buffer allocation

Mon Dec 9 10:49:08 CET 2019
Clean up the driver with the new managed buffer allocation API.
The normal playback streams need a workaround for the aligned buffer,
and cannot apply the straight snd_pcm_lib_malloc() stuff, so they
remain untouched, while other streams are converted to the new managed
mode.
Most of hw_params and hw_free callbacks became superfluous and got
dropped.
