[PATCH] Bluetooth: Annotate struct hci_drv_rp_read_info with __counted_by_le()

[PATCH] Bluetooth: Annotate struct hci_drv_rp_read_info with __counted_by_le()

[Thorsten Blum]

Add the __counted_by_le() compiler attribute to the flexible array
member 'supported_commands' to improve access bounds-checking via
CONFIG_UBSAN_BOUNDS and CONFIG_FORTIFY_SOURCE.
