Subject: ALSA: hda - Increase the max number of coverters/pins in patch_hdmi.c
X-Git-Tag: upstream/snapshot3+hdmi~7307^2~116^2~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a4567cb389301262f7ff392074eb3b0864498737;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

ALSA: hda - Increase the max number of coverters/pins in patch_hdmi.c

The new hardware tends to have more and more.  As a temporary fix, just
increase the number for now.

For a long-term solution, we should assign the cvts/pins dynamically.
