If anyone has any objections, please let me know. ------------------ From: Philipp Zabel [ Upstream commit d64c732dfc9edcd57feb693c23162117737e426b ] 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.
