1/* Linux driver for Philips webcam
2 Decompression for chipset version 1
3 (C) 2004-2006 Luc Saillard (luc@saillard.org)
4
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.
