mainlining shenanigans
If device tree is not enabled, of_find_regulator_by_node() should have a dummy function since the function call is still there. This is to fix build error after CONFIG_NO_AUTO_INLINE is introduced. If this option is enabled, GCC will not auto-inline functions that are not explicitly marked as inline. In this case (no CONFIG_OF), the copmiler will report error in function regulator_dev_lookup(). W/O NO_AUTO_INLINE, function of_get_regulator() is auto-inlined and then the call to of_find_regulator_by_node() is optimized out since of_get_regulator() always return NULL. W/ NO_AUTO_INLINE, the return value of of_get_regulator() is a variable so the call to of_find_regulator_by_node() cannot be optimized out. So we need a stub of_find_regulator_by_node(). static struct regulator_dev *regulator_dev_lookup(struct device *dev, const char *supply) { struct regulator_dev *r = NULL; struct device_node *node; struct regulator_map *map; const char *devname = NULL; regulator_supply_alias(&dev, &supply); /* first do a dt based lookup */ if (dev && dev->of_node) { node = of_get_regulator(dev, supply); if (node) { r = of_find_regulator_by_node(node); if (r) return r; ...

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. See Documentation/00-INDEX for a list of what is contained in each file. 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.
