Unless I am mistaken this driver does not really need the firmware structure past rpi_ts_probe(), and will be fine if it disappears earlier than unbind time.

Yes, I missed that. Will update it. Regards, Nicolas

Use devm_rpi_firmware_get() so as to make sure we release RPi's firmware interface when unbinding the device.
