Subject: [PATCH 3.2 072/153] firmware/dmi_scan: constify strings

3.2.102-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Jean Delvare <jdelvare@...e.de>

commit ffbbb96dd7570b9aafd426cd77a7ee03d224cabf upstream.

Add const to all DMI string pointers where this is possible.  This fixes a
checkpatch warning.
