From: Benjamin Tissoires Date: Sun, 5 Apr 2015 13:44:12 -0700 Subject: [PATCH] Input: Revert "Revert "synaptics - use dmax in input_mt_assign_slots"" This reverts commit 09d042a2eb90 ("Revert "Input: synaptics - use dmax in input_mt_assign_slots"") Now that balanced slots assignments seem to be fixed, let's re-enable the use in synaptics.c and wait for users to complain if there are still problems.
