    afs: Add missing afs_put_cell() · e4415015
    David Howells authored
    afs_alloc_volume() needs to release the cell ref it obtained in the case of
    an error.  Fix this by adding an afs_put_cell() call into the error path.
    This can triggered when a lookup for a cell in a dynamic root or an
    autocell mount returns an error whilst trying to look up the server (such
    as ENOMEDIUM).  This results in an assertion failure oops when the module
    is unloaded due to outstanding refs on a cell record.
    Fixes: d2ddc776 ("afs: Overhaul volume and server record caching and fileserver rotation")
