Subject: [PATCH v5 08/11] input: raspberrypi-ts: Release firmware handle when not needed
Date:   Mon, 23 Nov 2020 19:38:29 +0100

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

Changes since v3:
 - Release firmware handle in probe function

Changes since v2:
 - Use devm_rpi_firmware_get(), instead of remove function
