Subject: [FreeBSD] Fix long standing memory leak in drm_remove_magic.
X-Git-Tag: libdrm-2.4.0~68
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0687c0a4ec78730f752cee04a5b0862f47dbf026;p=platform%2Fupstream%2Flibdrm.git

[FreeBSD] Fix long standing memory leak in drm_remove_magic.

We shuffled all the links around to disconnect the entry, but
never free it.  We would incorrectly free the last entry in the
hash chain if nothing matched.
