-Subject: [PATCH] ALSA: usb-audio: Fix the missing ctl name suffix at parsing
- SU
-
-The commit 89b89d121ffc ("ALSA: usb-audio: Add check return value for
-usb_string()") added the check of the return value from
-snd_usb_copy_string_desc(), which is correct per se, but it introduced
-a regression.  In the original code, either the "Clock Source",
-"Playback Source" or "Capture Source" suffix is added after the
-terminal string, while the commit changed it to add the suffix only
-when get_term_name() is failing.  It ended up with an incorrect ctl
-name like "PCM" instead of "PCM Capture Source".
-
-Also, even the original code has a similar bug: when the ctl name is
-generated from snd_usb_copy_string_desc() for the given iSelector, it
-also doesn't put the suffix.
-
-This patch addresses these issues: the suffix is added always when no
-static mapping is found.  Also the patch tries to put more comments
-and cleans up the if/else block for better readability in order to
-avoid the same pitfall again.
