Public bug reported:
Attempting to build this package under kernel 4.6 or 4.2 results in
numerous errors, mainly with __devinit and __devexit .
I replace __devexit with __exit and __devinit with __init. I also
replaces calls to check_mem_region with calls to request_mem_region and
page_cache_release with put_page. The module then builds but the kernel
asserts at start up and fails to boot.
from the logs:

So it appears that my use of request_mem_region is probably wrong.
It would be really great to get this module going again as many
netbooks, including mine, have this card.
