Subject[PATCH 0/4] kconfig: rework symbol help text
This series fixes several issues with help text generated by Kconfig,
mainly affecting symbols that are defined in multiple places. Although
results of these patches are somewhat visible for the symbols in Linux,
what prompted me to write the series was working on U-Boot, which also
uses Kconfig and makes very heavy use of multiple definitions (e.g. for
overriding defaults). I have provided Linux examples where I could find
them, but the example for the biggest patch (the first one) is taken
from U-Boot because it was more illustrative than anything I could find
in Linux.

Thomas Hebb (4):
kconfig: list all definitions of a symbol in help text
kconfig: don't crash on NULL expressions in expr_eq()
kconfig: distinguish between dependencies and visibility in help text
kconfig: fix nesting of symbol help text
