Subject: Bluetooth: Add hci_sock_test_flag helper function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c85be545ea23a4fe590c89683242a9be823394e0;p=linux-beck.git

Bluetooth: Add hci_sock_test_flag helper function

The management interface will need access to the socket flags and so
provide a helper function for checking them.
