Changes since 20110701:
when CONFIG_PCI is not enabled:

drivers/misc/pti.c:410: error: implicit declaration of function 'pci_release_region'
drivers/misc/pti.c:859: error: implicit declaration of function 'pci_request_region'

Stubs for these 2 functions could be added to include/linux/pci.h, but it would
make more sense to me just to make the driver depend on PCI since it seems to rely
on so many PCI functions. or are the PCI pieces optional?
ping. still a problem in linux-next 20110706.
Thanks for the ping.

Is there something you need me to do or look at?

For Intel-Atom architectures, the MIPI PTI module does sit on the PCI
bus. It's very much dependent upon the PCI bus for working
functionality and it's not optional. So yes, it makes sense for the
driver to depend on PCI to be there and if PCI is not enabled on the
system, don't build the pti driver.

Maybe it's a Kconfig dependency?
Yes, please send/merge a patch that adds
depends on PCI
to "config INTEL_MID_PCI".
http://kisskb.ellerman.id.au/kisskb/buildresult/4292241/:
I can't access that http site (with or without the ':').

drivers/misc/pti.c:249: error: implicit declaration of function 'kmalloc'
drivers/misc/pti.c:258: error: implicit declaration of function 'kfree'
drivers/misc/pti.c:657: error: implicit declaration of function 'copy_from_user'
drivers/misc/pti.c:848: error: implicit declaration of function 'kzalloc'

Probably missing


#include<linux/slab.h>
#include<linux/uaccess.h>

I can send a patch to add these two includes. It didn't have previous troubles compiling, so maybe one of the other includes used to be including these?
