Hi Mauro,

The slab.h dependency was changed in the kernel 2.6.34 and its
inclusion in some gspca source files was needed in case of the usage of
kmalloc/kfree only.

After removing the JPEG header allocation, most gspca subdrivers do not
use alloc/free anymore, so, there is no need to include slab.h anymore.

On the other side, this patch is easily checked because, if wrong, it
raises compilation errors on any architecture.

Then, both patches (removal of JPEG alloc/free and slab.h inclusion)
should go to 2.6.36.

Cheers.
