icssg_prueth.c and icssg_prueth_sr1.c drivers use multiple common .c files. These common objects are getting added to multiple modules. As a result when both drivers are enabled in .config, below warning is seen. drivers/net/ethernet/ti/Makefile: icssg/icssg_common.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_classifier.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_config.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_mii_cfg.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_stats.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_ethtool.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 Fix this by building a new module (icssg.o) for all the common objects. Both the driver can then depend on this common module. Some APIs being exported have emac_ as the prefix which may result into confusion with other existing APIs with emac_ prefix, to avoid confusion, rename the APIs being exported with emac_ to icssg_ prefix. This also fixes below error seen when both drivers are built. ERROR: modpost: "icssg_queue_pop" [drivers/net/ethernet/ti/icssg-prueth-sr1.ko] undefined! ERROR: modpost: "icssg_queue_push" [drivers/net/ethernet/ti/icssg-prueth-sr1.ko] undefined!

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 reStructuredText 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.
