atmel_mxt_ts on droid4: powersave seems to break the driver

[Pavel Machek]

HI!

v4.17-rc1 on motorola droid 4.

If I disable/reenable touschreen with xinput, it fails, with this in
the logs:

[ 1633.749450] cpcap-usb-phy cpcap-usb-phy.0: connected to USB host
[ 1655.938751] atmel_mxt_ts 1-004a: __mxt_read_reg: i2c transfer
failed (-121)
[ 1655.945800] atmel_mxt_ts 1-004a: Failed to read T44 and T5 (-121)
[ 1663.829498] cpcap-usb-phy cpcap-usb-phy.0: connected to USB host

Unfortunately, xscreensaver seems to break it in a similar way.
