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. Fixes: 3ad796cbc36a ("ALSA: pcm: Use SG-buffer only when direct DMA is available") Reported-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/r/20200707111225.26826-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
