[v1,0/2] Bug fixes for qualcomm BT chip wcn3990.

When we set an KASAN flags, we are seeing an crash while removing module hci_uart.
This is due to dereference of hdev. As in module deinit we are calling function
hci_free_dev() to free hdev.
 
Changes in v1:
 
  * removed dereference of hdev in qca_power_shutdown i.e. qca_close.
  * moved serdev open & close call from qca_open & qca_close.


Balakrishna Godavarthi (2):
  Bluetooth: hci_qca: Remove serdev_device_open/close function calls
  Bluetooth: hci_qca: Remove hdev dereference in qca_close().
