| Subject: [PATCH] alsaucm: Fix ending with quotes commands |
| |
| Upstream status: |
| https://lore.kernel.org/alsa-devel/20200709062412.348-1-cyueh@chromium.org/T/ |
| |
| If we use 'alsaucm -n -b -' with 'get "CapturePCM/Internal Mic"' then |
| the alsaucm will report error and stop immediately. The reason is that |
| the parse_line in usecase.c appends an empty argument if a command ends |
| with quotes. |
| |
| This change adds a patch to fix the parse_line function in usecase.c. |
