modpost: always show verbose warning for section mismatch
Unless CONFIG_DEBUG_SECTION_MISMATCH is enabled, modpost only shows the number of section mismatches. If you want to know the symbols causing the issue, you need to rebuild with CONFIG_DEBUG_SECTION_MISMATCH. It is tedious. I think it is fine to show annoying warning when a new section mismatch comes in. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
