Subject: [PATCH] ALSA: memalloc: Drop superfluous snd_dma_buffer_sync() declaration
Git-commit: 7d2a0df24227337cf42b024c91708f542ca4ff90
Patch-mainline: v5.16-rc1
References: bsc#1192354

snd_dma_buffer_sync() is declared twice, and the one outside the ifdef
CONFIG_HAS_DMA could lead to a build error when CONFIG_HAS_DMA=n.
As it's an overlooked leftover after rebase, drop this line.

Fixes: a25684a95646 ("ALSA: memalloc: Support for non-contiguous page allocation")
