From 4b34ee782164fbaf29b2e7c0e8cb3a898c0986ca Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 21 Feb 2012 14:13:02 +0200 Subject: [PATCH] Bluetooth: mgmt: Fix powered checks for commands Having the HCI_AUTO_OFF flag set means that from a mgmt interface perspective we're still not powered, so all tests for HCI_UP should also include a test for HCI_AUTO_OFF. This patch adds a convenience macro for it.
