[PATCH 02/27] qemuProcessPrepareHostBackendChardevFileHelper: Always use FD passing
Peter Krempa

Wed Feb 9 16:01:54 UTC 2022
Code paths which don't wish to use FD passing are supposed to not call
the function which sets up the chardev for FD passing.
This is ensured by calling it only in the host prepare step.
