The BTMTKSDIO_BT_WAKE_ENABLED flag is set for bluetooth interrupt during system suspend and increases wakeup count for bluetooth event. Signed-off-by: Zhengping Jiang <jiangzp@google.com> --- Changes in v3: - Replace deprecated macro. Changes in v2: - Add Bluetooth prefix to patch subject - Fix warnings regarding using plain integer as NULL - Add static to btmtksdio_pm_ops Changes in v1: - Add BTMTKSDIO_BT_WAKE_ENABLED flag - Call pm_wakeup_event in btmtksdio_interrupt drivers/bluetooth/btmtksdio.c | 44 ++++++++++++++++++++++++++++++----- 1 file changed, 38 insertions(+), 6 deletions(-)
