From 467fd0e82b6265b8e6cc078a70bd7592574d5c83 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 7 Jul 2020 13:12:25 +0200 Subject: ALSA: pcm: Fix build error on m68k and others The commit 3ad796cbc36a ("ALSA: pcm: Use SG-buffer only when direct DMA is available") introduced a check of the DMA type and this caused a build error on m68k (and possibly some others) due to the lack of dma_is_direct() definition. Since the check is needed only for CONFIG_SND_DMA_SGBUF enablement (i.e. solely x86), use #ifdef instead of IS_ENABLED() for avoiding such a build error.
