From a608b6a646e8816bc0db156baad2e0679fa4d137 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 9 Sep 2020 07:16:37 +0900 Subject: [PATCH 1/3] kconfig: qconf: use delete[] instead of delete to free array (again) Commit c9b09a9249e6 ("kconfig: qconf: use delete[] instead of delete to free array") fixed two lines, but there is one more. (cppcheck does not report it for some reason...) This was detected by Clang. "make HOSTCXX=clang++ xconfig" reports the following: scripts/kconfig/qconf.cc:1279:2: warning: 'delete' applied to a pointer that was allocated with 'new[]'; did you mean 'delete[]'?

Move all declarations of menu.c functions below. BTW, some are declared in lkc.h and some in lkc_proto.h, but the difference is unclear. I guess some refactoring is needed.

I intended to drop duplicated "Symbol:", "Type:", but precious info about help and reverse dependencies was lost too. Revive it now.
