+Subject: DMI: allow omitting ident strings in DMI tables
+
+From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
+
+commit 75757507e014fa074d25d2883c4ab604999584bd upstream.
+
+The purpose of dmi->ident is twofold - it may be used by DMI callback
+functions when composing log messages; it is also used to determine
+end of DMI table in dmi_check_system() and dmi_first_match(). However,
+in case when callbacks are not interested in using ident at all it just
+wastes memory. Let's make entries with empty first match slot serve as
+end-of-table markers instead.
+
+[needed for DMI table changes that need to be done by later patches - gkh]
