6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: John Keeping <jkeeping@xxxxxxxxxxxxxxxxx> [ Upstream commit 9f0fad0382124e7e23b3c730fa78818c22c89c0a ] The caller of this function treats all non-zero values as an error, so the return value of i2c_master_recv() cannot be returned directly. This fixes touch reporting when there are more than 6 active touches.
