Based on device may wakeup status, Bluez stack will enable/disable passive scanning with whitelist in BT controller while suspending. As interrupt from BT SoC is handled by UART driver,we need to use device handle of UART driver to get the status of device may wakeup Signed-off-by: Venkata Lakshmi Narayana Gubba <gubbaven@codeaurora.org> --- drivers/bluetooth/hci_qca.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+)
