    Subject[ 038/108] Bluetooth: Fix using NULL inquiry entry
    Date
    From: Greg KH <gregkh@linuxfoundation.org>

    3.5-stable review patch. If anyone has any objections, please let me know.

    ------------------

    From: Ram Malovany <ramm@ti.com>

    commit c810089c27e48b816181b454fcc493d19fdbc2ba upstream.

    If entry wasn't found in the hci_inquiry_cache_lookup_resolve do not
    resolve the name.This will fix a kernel crash when trying to use NULL
    pointer.
