Subject: Revert "ALSA: line6: Only determine control port properties if needed"
From: Takashi Iwai <tiwai@xxxxxxx>
commit f3d83317a69e7d658e7c83e24f8b31ac533c39e3 upstream.
This reverts commit f6a0dd107ad0c8b59d1c9735eea4b8cb9f460949.
The commit caused a regression on LINE6 Transport that has no control
caps. Although reverting the commit may result back in a spurious
error message for some device again, it's the simplest regression fix,
hence it's taken as is at first. The further code fix will follow
later.
