Subject: libopkg: do not modify original version string in parse_version()
X-Git-Url: https://git.librecmc.org/?p=oweals%2Fopkg-lede.git;a=commitdiff_plain;h=eef0d1c9c56fb7c6733b716d36b08911639690dd

libopkg: do not modify original version string in parse_version()

The parse_version() function might be parsing the version string of another
pkg_t instance so we must not modify it inplace to truncate the revision
part, otherwise we will clobber the original version, leading to failing
comparisations later on.
