Bartosz Golaszewski says: ==================== net: stmmac: introduce devres helpers for stmmac platform drivers The goal of this series is two-fold: to make the API for stmmac platforms more logically correct (by providing functions that acquire resources with release counterparts that undo only their actions and nothing more) and to provide devres variants of commonly use registration functions that allows to significantly simplify the platform drivers. The current pattern for stmmac platform drivers is to call stmmac_probe_config_dt(), possibly the platform's init() callback and then call stmmac_drv_probe(). The resources allocated by these calls will then be released by calling stmmac_pltfr_remove(). This goes against the commonly accepted way of providing each function that allocated a resource with a function that frees it. First: provide wrappers around platform's init() and exit() callbacks that allow users to skip checking if the callbacks exist manually. Second: provide stmmac_pltfr_probe() which calls the platform init() callback and then calls stmmac_drv_probe() together with a variant of stmmac_pltfr_remove() that DOES NOT call stmmac_remove_config_dt(). For now this variant is called stmmac_pltfr_remove_no_dt() but once all users of the old stmmac_pltfr_remove() are converted to the devres helper, it will be renamed back to stmmac_pltfr_remove() and the no_dt function removed. Finally use the devres helpers in dwmac-qco-ethqos to show how much simplier the driver's probe() becomes. This series obviously just starts the conversion process and other platform drivers will need to be converted once the helpers land in net/. ==================== Link: https://lore.kernel.org/r/20230623100417.93592-1-brgl@bgdev.pl 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 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.
