A user reported:
'Use of uninitialized value $ENV{"LMC_KEEP"} in split at
 ./scripts/kconfig/streamline_config.pl line 596.'

so first check that $ENV{LMC_KEEP} is defined before trying
to use it.

Nathan,
I think adding your tag is OK to credit your contribution.
Please let me know if you do not have it in
the commit log.

Thanks, but I'd just as soon not be acknowledged/credited. All I did
was submit a report.

Even if you do not write the code,
reporting bugs is a great contribution,
and the Reported-by exists for that, I think.

So, I just want to add your Reported-by tag
(if you do not mind).

Heard, but all the same if it isn't important (which I'm assuming),
I'd just as soon be left out of it. That's just the way I am in
general, not wanting to be seen unless I have to be seen. Thanks
though.
