Re: input: elantech.c: adding comment lines for Fujitsu notebooks

[ulrik.debie-os@e2big.org]

Thanks Rainer,

According to the top bit of the first byte of the caps, the Fujitsu LIFEBOOK
E544 reports a trackpoint, the Fujitsu LIFEBOOK E554 does not.

This would mean that if you equip the E544 with a trackpoint, the trackpoint 
will work with the next kernel release, but the trackpoint of the E554, when 
the laptop is equipped with a trackpoint, will not.

I wonder if you can make the trackpoint work on the E554 when equipped
with trackpoint when you force the if test 
       /* The MSB indicates the presence of the trackpoint */
        if ((etd->capabilities[0] & 0x80) == 0x80) {
to always succeed ?

Thanks,
Kind regards,
Ulrik
