With ARCH=hexagon, make allmodconfig && make W=1 C=1 reports: WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/net/ethernet/synopsys/dwc-xlgmac.o With most other ARCH settings the MODULE_DESCRIPTION() is provided by the macro invocation in dwc-xlgmac-pci.c. However, for hexagon, the PCI bus is not enabled, and hence CONFIG_DWC_XLGMAC_PCI is not set. As a result, dwc-xlgmac-pci.c is not compiled, and hence is not linked into dwc-xlgmac.o. To avoid this issue, relocate the MODULE_DESCRIPTION() and other related macros from dwc-xlgmac-pci.c to dwc-xlgmac-common.c, since that file already has an existing MODULE_LICENSE() and it is unconditionally linked into dwc-xlgmac.o.

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.
