Subject: src/utils_avltree.c: Fix avl_get to work as documented.
X-Git-Tag: collectd-4.2.2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=3b915093d8cbc7738b2de59f6ebc38f195131002;p=collectd.git

src/utils_avltree.c: Fix avl_get to work as documented.

The documentation in the header file for avl_get states that value may be null,
but the code in the source file asserts otherwise. This patch changes the code
to reflect the documentation.
