From 9f61656a60c9506e3e4cd41af5efbcf6a30ee3b9 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 28 Apr 2011 11:28:54 -0700 Subject: Bluetooth: Add variable SSP auto-accept delay support Some test systems require an arbitrary delay to the auto-accept test cases for Secure Simple Pairing in order for the tests to pass. Previously when this was handled in user space it was worked around by code modifications and recompilation, but now that it's on the kernel side it's more convenient if there's a debugfs interface for it.
