Subject: ALSA: hdmi - dont fail on extra nodes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3eaead579ebc09d4f4c050c9b6ce6d67337bcb20;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ALSA: hdmi - dont fail on extra nodes

The number of HDMI nodes is expected to go up in future.
So don't fail hard on seeing extra converter/pin nodes.

We can still operate safely on the nodes within
MAX_HDMI_CVTS/MAX_HDMI_PINS.
