Russell King says: ==================== net: stmmac: hwif.c cleanups This series cleans up hwif.c: - move the reading of the version information out of stmmac_hwif_init() into its own function, stmmac_get_version(), storing the result in a new struct. - simplify stmmac_get_version(). - read the version register once, passing it to stmmac_get_id() and stmmac_get_dev_id(). - move stmmac_get_id() and stmmac_get_dev_id() into stmmac_get_version() - define version register fields and use FIELD_GET() to decode - start tackling the big loop in stmmac_hwif_init() - provide a function, stmmac_hwif_find(), which looks up the hwif entry, thus making a much smaller loop, which improves readability of this code. - change the use of '^' to '!=' when comparing the dev_id, which is what is really meant here. - reorganise the test after calling stmmac_hwif_init() so that we handle the error case in the indented code, and the success case with no indent, which is the classical arrangement. ==================== Link: https://patch.msgid.link/aQFZVSGJuv8-_DIo@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
