Subject: [PATCH] ALSA: memalloc: Add fall-through annotation
Git-commit: 3c4cfa7bf6075be035cff3cac0986395f6fca32b
Patch-mainline: v4.20-rc1
References: bsc#1121278
As a preparatory patch for the upcoming -Wimplicit-fallthrough
compiler checks, add the "fall through" annotation in
snd_dma_alloc_pages(). Note that this seems necessary to be put
exactly before the next label, so it's outside the ifdef block.
