Subject: [PATCH] darwin: namespace permission request loader function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The dummy function that's used to force the loading of objective-c
classes from a static permission plugin was not properly namespaced. We
name mangle it by appending the qt namespace.

Pick-to: 6.10
Task-number: QTBUG-138543
Change-Id: If8f634720fe1efac8626d4b429397bf463089f98
