/home/test/libsolv/ext/solv_xmlparser.c:294:25: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
294 | xmlErrorPtr err = xmlCtxtGetLastError(xmlp->parser);
| ^~~~~~~~~~~~~~~~~~~
The cause was that libxml2 2.12.0 changed a prototype of
xmlCtxtGetLastError(). This patch fixes it.
