From: Greg KH <[email protected]> 3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Ram Malovany <[email protected]> commit 7cc8380eb10347016d95bf6f9d842c2ae6d12932 upstream. If the device was not found in a list of found devices names of which are pending.This may happen in a case when HCI Remote Name Request was sent as a part of incoming connection establishment procedure. Hence there is no need to continue resolving a next name as it will be done upon receiving another Remote Name Request Complete Event. This will fix a kernel crash when trying to use this entry to resolve the next name.
