Since commitfd5736bf9f("enetc: Workaround for MDIO register access issue"), enetc_refill_rx_ring no longer updates the RX BD ring's consumer index, that is left to be done by the caller. This has led to bugs such as the ones found in96a5223b91("net: enetc: remove bogus write to SIRXIDR from enetc_setup_rxbdr") and3a5d12c9be("net: enetc: keep RX ring consumer index in sync with hardware"), so it is desirable that we move back the update of the consumer index into enetc_refill_rx_ring. The trouble with that is the different MDIO locking context for the two callers of enetc_refill_rx_ring: - enetc_clean_rx_ring runs under enetc_lock_mdio() - enetc_setup_rxbdr runs outside enetc_lock_mdio() Simplify the callers of enetc_refill_rx_ring by making enetc_setup_rxbdr explicitly take enetc_lock_mdio() around the call. It will be the only place in need of ensuring the hot accessors can be used. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
