Subject[PATCH v4 2/3] Bluetooth: btqcomsmd: use HCI_QUIRK_USE_BDADDR_PROPERTY
Date
Use the HCI_QUIRK_USE_BDADDR_PROPERTY quirk to let the HCI
core handle the reading of 'local-bd-address'. With this there
is no need to set HCI_QUIRK_INVALID_BDADDR, the case of a
non-existing or invalid fwnode property is handled by the core
code.

Changes in v4:
- btqcomsmd_setup(): removed unused variables 'err' and 'btq'

Changes in v3:
- none

Changes in v2:
- removed now unused field 'bdaddr' from struct btqcomsmd
- added 'Reviewed-by: Balakrishna Godavarthi <bgodavar@codeaurora.org>' tag
