Subject: vfs301: Fix device pointer handling in callback
|
|
|
|
When porting the driver to the new libfprint 1.90.0 a mistake was made
|
|
where the device was not passed through user_data anymore but it was
|
|
still read from there. Stop using user_data in the callback to fix this.
|
|
|
|
See: #320
