Use devm_rpi_firmware_get() so as to make sure we release RPi's firmware interface when unbinding the device. Signed-off-by: Nicolas Saenz Julienne <nsaenzjulienne@suse.de> --- Changes since v3: - Release firmware handle in probe function Changes since v2: - Use devm_rpi_firmware_get(), instead of remove function drivers/input/touchscreen/raspberrypi-ts.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
