Subject: ALSA: hda - Improve debug prints for output paths
X-Git-Tag: v3.9-rc1~52^2~77^2~18
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a769409cf325b697c439acef5d7c0dc4b6a591ba;p=platform%2Fkernel%2Flinux-stable.git

ALSA: hda - Improve debug prints for output paths

Print the information of outputs in a bit more details and concisely
in a single place instead of printing the path at each time when
detected.
