Subject: [PATCH] wacom: Provide connector name for disambiguation
|
||
|
|
|
||
|
|
Provide the connector name as the fourth value in the
|
||
|
|
tablet's output setting. With recent Mutter, this will
|
||
|
|
allow disambiguating the mapped output if there happens
|
||
|
|
to be multiple outputs with the same EDID data.
