[alsa-devel] [PATCH 10/24] ALSA: firewire: Convert to the common vmalloc memalloc

The recent change (*) in the ALSA memalloc core allows us to drop the special vmalloc-specific allocation and page handling. This patch coverts to the common code. (*) df3fd6509421: ALSA: memalloc: Add vmalloc buffer allocation support 6ef6be988f98: ALSA: pcm: Handle special page mapping in the default mmap handler
