It used to be a code that returns arror at ov7660_init.
However, this was removed by changeset c84e412f:

drivers/media/usb/gspca/m5602/m5602_ov7660.c:99:9: warning: variable 'err' set but not used [-Wunused-but-set-variable]
It should be noticed that the original error code was crappy, as it wasn't
returning any error if sensor init fails.
Fix it by returning an error if the sensor can't be initialized.

Instead use v4l2_dbg and v4l2_err. Note that the PDEBUG macro is kept to
make this patch-set less invasive, but it is simply a wrapper around
v4l2_dbg now. Most of the other changes are there to make the dev parameter
for the v4l2_xxx macros available everywhere we do logging.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Setting the H and V flip controls at webcam connection time prevents

Currently used registers 0xc5 and 0xc7 provide only a very coarse
adjustment possibility within a very small value range (0-3).
With registers 0x01 and 0x03, a fine grained adjustment with
