[PATCH 2/2] staging: pi433: fix naming when more than one radio is used

From: Marcin Ciupak
Date: Mon Nov 20 2017 - 16:57:30 EST


When using more than one hardware radio module pi433_probe fails as the
same name is used for all modules. Create unique name by adding minor
number to the device name.
