[PATCH 5.7 187/244] Revert "Input: elants_i2c - report resolution information for touch major"

From: Greg Kroah-Hartman
Date: Mon Jul 20 2020 - 12:14:04 EST


From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>

commit 93b9de223c0135db495c25334e66cb669bef13e2 upstream.

This reverts commit 061706716384f1633d3d5090b22a99f33f1fcf2f - it turns
out that the resolution of 1 unit per mm was not correct for a number of
touch screens, causing touch sizes to be reported as way too large.
