From b576e6f236fd374421287f39542a9e26608406ff Mon Sep 17 00:00:00 2001 From: Kevin Chiu Date: Sat, 4 Feb 2017 03:55:01 +0800 Subject: Revert "google/pyro: remove Wacom touchscreen probed flag" Reason for revert: Pyro has two touchscreen sources: WACOM/ELAN. It will not have both touchscreen IC in one system at the same time. So the "probed" property of WACOM i2c device is mandatory to set for kernel to know whether it exists before driver initializes it. Otherwise in ELAN case, when driver fails to init WACOM i2c device, ACPI _OFF will be invoked to set GPIO#152 low to cut off power.
