[pwc] V4L2_CID_CONTRAST bug?

[Sander Jansen <>]

If I try to set the contrast of my Logitech Quickcam Pro 3000, the incorrect 
value is set by the driver:

case V4L2_CID_CONTRAST
        c->value <<= 8; 
        ret = pwc_set_contrast(pdev, c->value);
        
In pwc_set_contrast the value then gets incorrectly set:
        buf = (value >> 10) & 0x3f;

Changing c->value <<=8 to c->value <<=10 should do the trick.

Thanks,
        Sander
