Subject: [PATCH 02/13] tpm atmel: Call request_region with the correct base

Commit e0dd03caf20d040a0a86b6bd74028ec9bda545f5
changed the code path here so that ateml_get_base_addr
no longer directly altered the tpm_vendor_specific
structure, and instead placed the base address on the stack.

The commit missed updating the request_region call, which
would have resulted in request_region being called with 0
as the base address.

I don't know if request_region(0, ..) will fail, if so the
driver has been broken since 2006 and we should remove it
from the tree as it has no users.
