From 523ca58b7db2e30e3c185a7927dd80a30c1bc743 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 9 Feb 2018 01:19:08 +0900 Subject: [PATCH] kconfig: remove const qualifier from sym_expand_string_value() This function returns realloc'ed memory, so the returned pointer must be passed to free() when done. So, 'const' qualifier is odd. It is allowed to modify the expanded string.
