[linux-dvb] av7110 error handling

[Michael Schaefer <michael.schaefer@init-bs.com>]

Hi,

after looking at the driver source (DVB,HEAD,av7110) to find the reason why 
I've got those outcom errors (see 'Problems with low signal strength' 
thread) I asked myself what might be the reason that most of the error 
conditions returned by 'OutCommand' or 'Start/StopHWFilter' are ignored and 
not returned to the calling program (returning -1 from the ioctl handler 
and setting errno to a proper value).

As it is now, most of the ioctl's seem to be fire and forget, I do for 
example a STOP_DEMUX, get a return value of 0 but it did not work at all, 
continue with the program execution and things get worse.

Michael
