[PATCH] ov511 1.62 for 2.5.34

 Update the ov511 driver to version 1.62:
 o Update email address
 o Remove some dead code and fix some harmless typos
 o New device: Alpha Vision Tech. AlphaCam SE
 o Fix assignment of ov->proc_button->owner to not cause
   NULL pointer deref (credit: Oleg K.)
 o Support I2C read/write ioctl()s via V4L (credit: Oleg K.)
 o Add OV518-specific register dump code
 o New snapshot reset sequence; old one was causing
   erroneous I2C writes (credit: Oleg K.)
 o OV6630 needs different register 0x14 settings than OV6620
 o Don't print palette errors by default
 o Detect OV518 cameras that have packet numbering enabled
   by default and set ov->packet_numbering accordingly. This
   should fix the problems some users were having with babble
   (USB error -75) and cameras not working at all.

or so lines higher than the red component. This is only apparent in
