From 922021854bd8a0221fcb05aec2c13409cffb924e Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Fri, 18 Oct 2013 16:38:10 -0700 Subject: [PATCH] Bluetooth: Expose debugfs entry read/write own address type For some testing it is important to know the current own addres type, but also be able to change it. The change is lost over powery cycles and only intended for debugging.
