ubi: fastmap: Don't flush fastmap work on detach
commit 29b7a6fa1ec07e8480b0d9caf635a4498a438bf4 upstream. At this point UBI volumes have already been free()'ed and fastmap can no longer access these data structures. Reported-by: Martin Townsend <mtownsend1973@gmail.com> Fixes: 74cdaf24004a ("UBI: Fastmap: Fix memory leaks while closing the WL sub-system") Cc: stable@vger.kernel.org Signed-off-by: Richard Weinberger <richard@nod.at> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
