HID: i2c-hid: reset Synaptics SYNA2393 on resume
On the Dell XPS 9570, the Synaptics SYNA2393 touchpad generates spurious interrupts after resuming from suspend until it receives some input or is reset. Add it to the quirk I2C_HID_QUIRK_RESET_ON_RESUME so that it is reset when resuming from suspend. More information about the bug can be found in this mailing list discussion: https://www.spinics.net/lists/linux-input/msg59530.html Signed-off-by: Daniel Playfair Cal <daniel.playfair.cal@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
