Subject: [PATCH] Input: synaptics - fix regression with "image sensor"
|
|
trackpads
|
|
|
|
commit 7968a5dd492ccc38345013e534ad4c8d6eb60ed1
|
|
Input: synaptics - add support for Relative mode
|
|
|
|
Accidentally broke support for advanced gestures (multitouch)
|
|
on some trackpads such as the one in my ThinkPad X220 by
|
|
incorretly changing the condition for enabling them. This
|
|
restores it.
