Subject: [PATCH 099/181] synaptics: Fix problem after match is failed
|
|
|
688edb |
|
|
|
688edb |
This fixes the the problem that the sensor becomes unresponsive after
|
|
|
688edb |
pressing the wrong fingerprint. We fix the problem by making sure that
|
|
|
688edb |
the non-match report is delayed until the finger is removed. With this
|
|
|
688edb |
we cannot run into the situation that the next match request fails
|
|
|
688edb |
immediately as the finger is still present.
|
|
|

|
|

Fixes: #208
