charset="utf-8" From: Markus Armbruster Functions that use an Error **errp parameter to return errors should not also report them to the user, because reporting is the caller's job. When the caller does, the error is reported twice. When it doesn't (because it recovered from the error), there is no error to report, i.e. the report is bogus. qemu_rdma_source_init() and qemu_rdma_accept() violate this principle: they call error_report() via qemu_rdma_reg_control(). I elected not to investigate how callers handle the error, i.e. precise impact is not known. Clean this up by dropping the error reporting from qemu_rdma_reg_control(). I believe the callers' error reports suffice. If they don't, we need to convert to Error instead.
