Log:
xpp: xpd_fxs: ring_trapez parameter

This adds module parameter 'ring_trapez'. When set, the wave form of
the ring tone is set to be a trapezoid, rather than sine. Thus making
the ring stronger.

This is a boolean parameter of the module xpd_fxs. Takes effect at the
beginning of the next ring.
