Bit 2 is set anyway, bits 0 and 1 are read-only.
Your patch would not change anything...

I suggest to delay that until the LNBP21 code is factored out into a
separate file. Currently there are at least 3 lnbp21 implementations
in the driver tree.

Nak. You must not enable high voltage by default.

Maybe it would be useful to add a module parameter 'high_lnb_voltage'
to dvb_frontend.c. This way cable length compensation could be enabled
if the application software does not support the ioctl.
