| |
3.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit 69f9ba9b0cad67bc03f0a096f7f274de795ca844 upstream.
The regression-fix in 3.1 for the check of DMA-position validity caused yet another regression for CA0110. As usual, this hardware seems working only with LPIB properly. Adding the appropriate driver-caps bit to force LPIB fixes the problem.
