Subject: ALSA: ctxfi: Fix the incorrect check of dma_set_mask() call

From: Takashi Iwai <[email protected]>

commit f363a06642f28caaa78cb6446bbad90c73fe183c upstream.

In the commit [15c75b09f8d1: ALSA: ctxfi: Fallback DMA mask to 32bit], I forgot to put "!" at dam_set_mask() call check in cthw20k1.c (while cthw20k2.c is OK). This patch fixes that obvious bug.

(As a side note: although the original commit was completely wrong,
it's still working for most of machines, as it sets to 32bit DMA mask in the end. So the bug severity is low.)
