Subject: Bluetooth: Disable FCS only for new HS channels
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=12d6cc60f2d02d5754ca662b414f8f96200b14a6;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Disable FCS only for new HS channels

Set chan->fcs to L2CAP_FCS_NONE only for new L2CAP channels
(not moved). Other side can still request to use FCS.
