/* Linux driver for Philips webcam (C) 2004-2006 Luc Saillard (luc@saillard.org) NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx driver and thus may have bugs that are not present in the original version. Please send bug reports and support requests to <luc@saillard.org>. The decompression routines have been implemented by reverse-engineering the Nemosoft binary pwcx module. Caveat emptor.
