Subject: Bluetooth: Add white list lookup for incoming connection requests
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a55bd29d522729e0cb125474396acdc2a107d4d9;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Bluetooth: Add white list lookup for incoming connection requests

This patch adds support for looking up entries in the white list when
HCI_CONNECTABLE is not set. The logic is fairly simple: if we're
connectable check the black list, if we're not connectable check the
white list.
