[PATCH] tpm2: Export tpm2_get_cc_attrs_tbl for ibmvtpm driver as module

[Stefan Berger]

From: Stefan Berger <stefanb@linux.ibm.com>

This patch fixes the following problem when the ibmvtpm driver
is built as a module:

ERROR: modpost: "tpm2_get_cc_attrs_tbl" [drivers/char/tpm/tpm_ibmvtpm.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:94: __modpost] Error 1
make: *** [Makefile:1298: modules] Error 2

Hi, wrong tag (we use "tpm:"), missing fixes tag and please cc stable.
Thanks.

I did not add the fixes tag because I do not know the final commit hash, 
or is it the final commit hash once it is in linux-next? I doubt it with 
all the merging that can occur.

Can you send me a new version after rc1 is out?

Michael Ellerman (cc'ed) told me that the fixes tag should 'work' once 
the bad patch is in linux-next. So I reposted yesterday (with a stray 
'q' in the title :-( ):
