HID: i2c-hid: reset Synaptics SYNA2393 on resume
[ Upstream commit 538f67407e2c0e5ed2a46e7d7ffa52f2e30c7ef8 ]
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.
