Subject: [PATCH RESEND v2 06/11] PCI: dwc: Drop duplicated fast-link-mode flag unsetting
Date: Mon, 13 Mar 2023 23:08:10 +0300	[thread overview]
Message-ID: <20230313200816.30105-7-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20230313200816.30105-1-Sergey.Semin@baikalelectronics.ru>

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.
