KT Liao 969eeef398 Input: elan_i2c - clear INT before resetting controller
[ Upstream commit 4b3c7dbbff ]

Some old touchpad FWs need to have interrupt cleared before issuing reset
command after updating firmware. We clear interrupt by attempting to read
full report from the controller, and discarding any data read.
