Subject: [PATCH 0742/1085] input: goodix: Include I2C details in names for the
|
||
|
|
devices
|
||
|
|
|
||
|
|
libinput uses the input device name alone. If you have two
|
||
|
|
identical input devices, then there is no way to differentiate
|
||
|
|
between them, and in the case of touchscreens that means no
|
||
|
|
way to associate them with the appropriate display device.
|
||
|
|
|
||
|
|
Add the I2C bus and address to the start of the input device
|
||
|
|
name so that the name is always unique within the system.
|
||
