Subject: [PATCH v4 05/14] PCI: dwc: Drop duplicated fast-link-mode flag unsetting
Date:   Fri, 14 Apr 2023 05:18:23 +0300

Most likely by mistake the PORT_LINK_FAST_LINK_MODE flag unsetting was
added twice in the commit cff9244432e8 ("PCI: dwc: Ensure FAST_LINK_MODE
is cleared"): first it is cleared right after the content of the
PCIE_PORT_LINK_CONTROL register is read, second it's cleared in the
framework of the link-mode initialization procedure. The later action is
redundant. Let's drop it.
