Hi,
do you know any reason (i.e. a special device needs this) why switch to
register page 0 is done twice in the setcolors() function of pac7311?
I removed the redundant page switch and my Labtec Webcam 2200 still
behaves correctly when I change the "Saturation" control.
Regards,
Márton Németh

Remove redundant register page switching to page 0 when changing the
color control.
The change was tested with Labtec Webcam 2200 (USB ID: 093a:2626).
