[pwc] FC5, pwc-10.0.11 works, 10.0.12-rc1 fails with gyach

[Derek Atkins <>]

Hi,

I've got FC5, removed the kernel-provided pwc.ko, and tried building
pwc-10.0.12-rc1.  There was a compile warning:

... but the module loaded fine.  camstream works fine, but when I try
to use gyach it fails with the following log entry:

Jul 19 20:36:38 cliodev kernel: pwc: Wrong size (233472) needed to be
len_per_image=462848 or total_size=925696

I backed out to 10.0.11 and it compiled with no errors and it works
perfectly with both camstream and gyach.  I don't know what changed
between .11 and .12-rc1, but it's not quite perfect, yet.

PS: here's the log from when I plug in the webcam:
