From: Takashi Iwai Date: Mon, 9 Dec 2019 09:49:07 +0000 (+0100) Subject: ALSA: emu10k1x: Use managed buffer allocation X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=63832bd951d2c1deed3ea2dd5a74604902a1a0d1;p=linux.git ALSA: emu10k1x: Use managed buffer allocation Clean up the driver with the new managed buffer allocation API. The superfluous snd_pcm_lib_malloc_pages() and snd_pcm_lib_free_pages() calls are dropped.
