[ Upstream commit 8670b2b8b029a6650d133486be9d2ace146fd29a ]
udev has a feature of creating /dev/<node> device-nodes if it finds a devnode:<node> modalias. This allows for auto-loading of modules that provide the node. This requires to use a statically allocated minor number for misc character devices.
However, rfkill uses dynamic minor numbers and prevents auto-loading of the module. So allocate the next static misc minor number and use it for rfkill.
