Commit f072181e6403b0fe2e2aa800a005497b748fd284,
kconfig: drop the ""trying to assign nonexistent symbol" warning.
This warning actually helps detecting symbol renames which are lost in
translation which is helpful when doing oldconfigs etc.
Good argument. I like it.
When I update kconfig, then I overwrite it with the new version. Then I
apply the patches from scripts/ptx-modifications/. So any local changes
must be added there too. Can you do that? Just add exactly this patch there
and add it to the series file. Then amend the commit or create a second
one. Either way works for me.

Will do. Btw. This obviously applies to other projects using
kconfig/lxdialog. Kernel, busybox etc. I've always found that the
developers do not care for unassigned symbols in defconfigs etc. I am
currently trying to push this back into the kernel as it has approx 1k
unassigned symbols over arch defconfigs (ARM has around 450). Even
really, really old symbols.
But for the embedded developer for a project, coming from an old version
and upgrading kernel, busybox, whatever with oldconfig, a lot of symbols
are renamed over time and functionality "lost" without as much as a
notice. Sometimes that leads to time waste because you did not notice
the symbol name change.
Which has always bugged me. Ever since that was deleted in 2008.
So probably helpful for those pesky Busybox updates too (tnx) :)
