Hello,
This patch is reversing changes introduced in commit
02d04254a5dfb8de1459805c3433cd0e9e4853d7 (Input: alps - use struct
input_mt_pos to track coordinates), maybe some others, too. Is this
deliberate?
These are two examples of that.
[...]
* The bitmaps don't have enough data to track fingers, so this function
* only generates points representing a bounding box of at most two contacts.
- * These two points are returned in fields->mt.
+ * These two points are returned in x1, y1, x2, and y2.
*/
