[linux-dvb] power management is enabled by default now

[Holger Waechtler <holger@convergence.de>]

Hi everybody,

power management is enabled by default now, the default timeout after 
device release is 5 seconds. This means that LNB voltages are switched 
of about 5 seconds and you won't see any picture anymore unless you keep 
the frontend file descriptor open.

You can control this behaviour using the 'dvb_shutdown_timeout' module 
parameter. When you set 'dvb_shutdown_timeout=0' power management is 
disabled.

Those of you who use the DVB driver for networking might want to add 
this line to your modules.conf:

    options dvb-core dvb_shutdown_timeout=0

When you load the driver using 'make insmod' the Makefile will override 
this option and disable power management for now. This might change soon.

Holger
