-* Fix for Samsung MPC models, appearantly they are based on a newer chipset
-
-8.11
-
-* 20 dev_hints (per request)
-* Hot unplugging should be better, no more dangling pointers or memory leaks
-* Added reserved Logitech webcam IDs
-* Device now remembers size & fps between close()/open()
-* Removed palette stuff altogether
-
-8.10.1
-
-* Added IDs for PCVC720K/40 and Creative Labs Webcam Pro
-
-8.10
-
-* Fixed ID for QuickCam Notebook pro
-* Added GREALSIZE ioctl() call
-* Fixed bug in case PWCX was not loaded and invalid size was set
-
-8.9
-
-* Merging with kernel 2.5.49
-* Adding IDs for QuickCam Zoom & QuickCam Notebook
-
-8.8
-
-* Fixing 'leds' parameter
-* Adding IDs for Logitech QuickCam Pro 4000
-* Making URB init/cleanup a little nicer
-
-8.7
-
-* Incorporating changes in ioctl() parameter passing
-* Also changes to URB mechanism
-
-8.6
-
-* Added ID's for Visionite VCS UM100 and UC300
-* Removed YUV420-interlaced palette altogether (was confusing)
-* Removed MIRROR stuff as it didn't work anyway
-* Fixed a problem with the 'leds' parameter (wouldn't blink)
-* Added ioctl()s for advanced features: 'extended' whitebalance ioctl()s,
- CONTOUR, BACKLIGHT, FLICKER, DYNNOISE.
-* VIDIOCGCAP.name now contains real camera model name instead of
- 'Philips xxx webcam'
-* Added PROBE ioctl (see previous point & API doc)

-* Changed interface to decompressor module.
-* Cleaned up pwc structure a bit.
-
-7.0
-
-* Fixed bug in vcvt_420i_yuyv; extra variables on stack were misaligned.
-* There is now a clear error message when an image size is selected that
- is only supported using the decompressor, and the decompressor isn't
- loaded.
-* When the decompressor wasn't loaded, selecting large image size
- would create skewed or double images.
-
-6.3
-
-* Introduced spinlocks for the buffer pointer manipulation; a number of
- reports seem to suggest the down()/up() semaphores were the cause of
- lockups, since they are not suitable for interrupt/user locking.
-* Separated decompressor and core code into 2 modules.
-
-6.2
-
-* Non-integral image sizes are now padded with gray or black.
-* Added SHUTTERSPEED ioctl().

-6.1
-
-* VIDIOCSPICT returns -EINVAL with invalid palettes.
-* Added saturation control.
-* Split decompressors from rest.
-* Fixed bug that would reset the framerate to the default framerate if
