PWC driver changes

PWC driver changes

[Jeremy]

This whole affair is especially disappointing for me, as I just got a Phillips 
webcam up and running the other day using pwcx.  Will some kind soul please 
post something indicating which files contained the hook?  Was it part of pwc 
somewhere?  I'd like to compare the older kernel sources I have to the 2.6.8 I 
just downloaded so I can see what I need to change in order to keep pwcx 
working.

I received mine just one day too late... And I guess I'm not the only one. 
The fact that I bought it especially because of Linux support after trying 
3 other cams last week, adds some irony to ease the bitterness. :)

Yes. I assume it's all the stuff that contains the word 'decompressor'. 
Such as:

-       pdev->decompressor = NULL;
+       /* Find our decompressor, if any */
+       pdev->decompressor = pwc_find_decompressor(pdev->type);

You can easily do a diff between the previous kernel version and a more 
recent one without the hooks.

Here's the patch that removed the whole driver:
http://linux.bkbits.net:8080/linux-2.6/gnupatch@412d8e0cqutBsdGubqorXXCeHHdS2g

You can reverse-patch this and then do a diff compare between the tree and 
the pwc-9.0.2 package. Or find the patchset that removed the hook.

A quick look with diff shows changes in:
./pwc-ctrl.c
./pwc-if.c
./pwc-uncompress.h
./pwc.h

Do email Philips customer support though. Let them know you use linux, 
bought their product and want a driver.
