L_LINT macro is used with negative numbers [i.e. L_LINT(time_freq, -MAXFREQ)], it could cause undefined behavior. It should be similar to the L_RSHIFT(v, n) macro. MFC after: 2 weeks Reviewed by: cy Pull Request: #769 Signed-off-by: Dmitriy Alexandrov <d06alexandrov@gmail.com>

L_LINT macro is used with negative numbers (e.g
L_LINT(time_freq, -MAXFREQ)
) so it could cause undefined behavior.So it should be similar to the L_RSHIFT(v, n) macro.
