From: Johan Hedberg <redacted> Since the clear_uuids operation doesn't send an immediate HCI command but just sets off a timer to wait for subsequent add_uuid calls it doesn't make sense to wait until the timer fires off to send the response. Instead send the response immediately. Signed-off-by: Johan Hedberg <redacted> --- net/bluetooth/mgmt.c | 23 +++++++++++++++++++---- 1 files changed, 19 insertions(+), 4 deletions(-)
