This patch fixes several return value related problems in zr364xx.
- return -ENOMEM instead of -ENODEV on out of memory
- zr364xx checks video_register_device() error only when
its return value is -1. But video_register_device() doesn't
always return -1 on error.
- If usb_register() returns error, module_init() wrongly returns 1:
retval = usb_register(&zr364xx_driver) < 0;
...
return retval;
And it allows the module to be loaded. Because sys_init_module() doesn't
see positive return value as error.

Some code to swap bytes wasn't using the swab16() function that the
kernel provides for this. Make use of it, which results in more
efficient code.

Add a missing header to fix compilation issue in the zr364xx driver when
CONFIG_VIDEO_V4L1 and CONFIG_VIDEO_V4L1_COMPAT are not set.

I did some change on the zr364xx driver following your comments:
* I replaced hardcoded values for initialization methods,
unfortunately I don't have nicer names to give for now.
* I removed the DBG() on all ioctl2 functions and used the .debug var
instead.
* Following a comment on linux-usb-devel I misunderstood, I added an
endianness test which was an error, so I removed it (the order of
the bytes in the JPEG header should not depend on endianness).

compat.h was missing from usbvideo-i2c.c and zr364xx.c
zr364xx.c needed the struct semaphore -> struct mutex compat check.
Added an old i2c id to compat.h. These could be added to the Hg copy of
linux/i2c-id.h instead? There's just this one so far.
zr364xx needs 2.6.15 because of vm_insert_page(), so add to versions.txt
