multiple saa7130 chipsets problem

multiple saa7130 chipsets problem

[Łukasz Łukojć]

Hi

I'm using 8 x saa7130hl chipset  based surveillance card and recently 
bought another one.
Just wanted to achieve 16 channels for cams recording.
Problem is that saa7134 module will only see eight integrals of card 
array 'card=x,x,x,x,x,x,x,x' and while i'm putting 
'card=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x' - dmesg will print 

card: can only take 8 arguments
saa734: '69' invalid for parameter 'card'

Modprobing with 'only' eight parameters will result that saa714 will be 
try to autodetect chipsets, which is appraently ends with hang errors.
Is there a siple hack to ovverride this behaviour ?

You could try modifying

	#define SAA7134_MAXBOARDS 8

in linux/drivers/media/video/saa7134/saa7134.h and recompiling.
