Subject: Bluetooth: Remove duplicated code in l2cap conn req
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9b27f350688c9399da10c2b888c4044c2c1bd923;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Remove duplicated code in l2cap conn req

The same sequence sending L2CAP Connection Request was used in several
places. Using subroutine makes those places easy to read.
