[PATCH v4 04/14] PCI: bt1: Fix printing false error message

From: Serge Semin
Date: Thu Apr 13 2023 - 22:19:31 EST


The dev_err_probe() method is supposed to be invoked only if any error is
happened. It was definitely wrong to call it unconditionally. Due to that
the DWC PCIe host initialization error-message is printed all the time the
Baikal-T1 PCIe controller is probed even if no error actually happened.
