The in kernel version of the pwc driver has never supported snapshot mode, and now that we no longer support the pixfmt.priv abuse there also no longer is a way for userspace to request it, rendering all the code in question dead (never called), so remove it.

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.
