[RFC v2 13/15] Bluetooth: Add thread-safe version of helpers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch adds the thread-safe version of helper functions to add
and remove pending auto connections. These helpers will be used in
next patches to implementing the Mgmt add/remove connection
parameters commands.
