Date: Mon, 13 Feb 2017 05:04:23 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Igor Zinovev <zinigor@...il.com>, Takashi Iwai <tiwai@...e.de> Subject: [PATCH 4.9 51/60] Revert "ALSA: line6: Only determine control port properties if needed" 4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <tiwai@...e.de> 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.
