From 020e773f6b2e797a13d23723773ed1b3ba2c35dc Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Mon, 1 Nov 2010 21:01:44 +0000 Subject: kconfig: sym_expand_string_value: allow for string termination when reallocing When expanding a parameterised string we may run out of space, this triggers a realloc. When computing the new allocation size we do not allow for the terminating '\0'. Allow for this when calculating the new length.
