   1/* Linux driver for Philips webcam
   2   Decompression for chipset version 1

   5   NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx
   6   driver and thus may have bugs that are not present in the original version.
   7   Please send bug reports and support requests to <luc@saillard.org>.
   8   The decompression routines have been implemented by reverse-engineering the
   9   Nemosoft binary pwcx module. Caveat emptor.
