[PATCH 1/9] Bluetooth: mgmt: Fix powered checks for commands

From: Johan Hedberg <redacted> 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. Signed-off-by: Johan Hedberg <redacted> --- net/bluetooth/mgmt.c | 26 ++++++++++++++------------ 1 files changed, 14 insertions(+), 12 deletions(-)
