Allow probing rfkill-gpio via device tree. This hooks up the already existing support that was started in commit 262c91ee5e52 ("net: rfkill: gpio: prepare for DT and ACPI support") via the "rfkill-gpio" compatible, with the "name" and "type" properties renamed to "label" and "radio-type", respectively, in the device tree case. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> --- Changes since v1: - Use __maybe_unused instead of #ifdef CONFIG_OF (Krzysztof) - Support renamed "label" and "radio-type" property names --- net/rfkill/rfkill-gpio.c | 20 ++++++++++++++++++-- 1 file changed, 18 insertions(+), 2 deletions(-)
