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

As complained by gcc:
drivers/media/usb/gspca/m5602/m5602_ov7660.c: In function 'ov7660_init':
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.
