Subject: [PATCH 0/2] firmware: dmi: Avoid (some) empty names in kernel log

Hi,

 I've noticed one of my systems shows this output in the kernel log:

Legacy DMI 2.0 present.
DMI:  /i430HX, BIOS 4.51 PG 05/13/98

which leaves something to desire.  While the contents of /sys/firmware/dmi 
remain the main source of DMI data, along with output from `dmidecode', 
the summary from the kernel log is often readily available with various 
reports, making it a point of easy reference.  Therefore I think empty 
names are best avoided if possible.

 The system in question is a Tyan Tomcat IV S1564D mainboard, which has 
its System Information all empty, not unreasonably as it was sold as a 
bare board for field integration rather that a complete system.  It does 
have the manufacturer correctly recorded with Base Board Information 
though.

 I have therefore made this mini patch series, with 2/2 printing the board 
manufacturer if none has been given for the system, and including 1/2 as 
well to prevent a trailing slash with an empty board name, following my 
observation made with an unrelated issue where the reporter included a log 
with just "/" shown as the system name.

 See individual change descriptions for further details.

 Please apply.
