Subject: Bluetooth: Refactor ACL connection into its own function
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=db4742756ae2a836618cd5acf599522573589149;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Refactor ACL connection into its own function

The hci_connect() function was starting to get too complicated to be
quickly understood. We can separate the creation of a new ACL
connection into its own function.
