input: touch: synaptics: Reset the device when blanking display

This should be backed out as soon as fixed firmware becomes available!

Something is iffy with the controller that gets triggered under
certain environmental conditions and makes it hang or register ghost
touches for a few minutes. Instead of waiting for it to fix itself,
have the controller forcefully reset whenever the panel is cycled so
a manual recovery is possible.

This is not a fix or a workaround, just a recovery mechanism :(

net/l2tp: don't fall back on UDP [get|set]sockopt

The l2tp [get|set]sockopt() code has fallen back to the UDP functions
for socket option levels != SOL_PPPOL2TP since day one, but that has
never actually worked, since the l2tp socket isn't an inet socket.

As David Miller points out:

  "If we wanted this to work, it'd have to look up the tunnel and then
   use tunnel->sk, but I wonder how useful that would be"

Since this can never have worked so nobody could possibly have depended
on that functionality, just remove the broken code and return -EINVAL.
