Mainline Linux tree for various devices, only for fun :)

If a GPIO descriptor is passed to the regulator_register() function inside the config->ena_gpiod callers must be sure that once they call this API the regulator core owns that descriptor and will make sure to issue gpiod_put() on it, no matter whether the call is successful or not. For device tree regulators, the regulator core will automatically set up regulator init data from the device tree when registering a regulator by calling regulator_of_get_init_data() which in turn calls down to the regulator driver's .of_parse_cb() callback. This callback (in drivers such as for max77686) may also choose to fill in the config->ena_gpiod field with a GPIO descriptor. Harden the errorpath of regulator_register() to properly gpiod_put() any passed in cfg->ena_gpiod or any gpiod coming from the device tree on any type of error.

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.
