From 51a8efd7d02c13cb1c6fdd1cd66788792a3fcc7c Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 16 Jan 2012 06:10:31 +0200 Subject: Bluetooth: Rename conn->pend to conn->flags These flags can and will be used for more general purpose values than just pending state transitions so the more common name "flags" makes more sense than "pend".
