From 7df26b56297456a133b8cc2efb069065d6b9a555 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 11 Nov 2015 12:24:21 +0200 Subject: [PATCH] Bluetooth: Pass inquiry length to bredr_inquiry() Passing the needed inquiry length to bredr_inquiry() makes it possible to also use this helper for interleaved discovery where the controller doesn't support simultaneous Inquiry & LE scan.
