_regulator_get() contains a lot of common code doing checks prior to the regulator lookup and housekeeping work after the lookup. Almost all the code could be shared with a OF-specific variant of _regulator_get(). Split out the common parts so that they can be reused. The OF-specific version of _regulator_get() will be added in a subsequent patch. No functional changes were made. Signed-off-by:

The behavior of regulator_dev_lookup() for non-DT way has been broken since the commit b8c32554 ("regulator: Move OF-specific regulator lookup code to of_regulator.c"). Before the commit, of_get_regulator() was used to get the regulator, which returns NULL if the regulator is not found. So the regulator will be looked up through regulator_lookup_by_name() if no matching regulator is found in regulator_map_list. However, currently, of_regulator_dev_lookup() is used to instead of of_get_regulator(), but the variable 'r' is set to ERR_PTR(-ENODEV) instead of NULL if the regulator is not found. In this case, if no regulator is found in regulator_map_list, the variable 'r' is still ERR_PTR(-ENODEV), So regulator_dev_lookup() returns the value of 'r' directly instead of continuing to look up the regulator through regulator_lookup_by_name().

Merge series from Andre Przywara <andre.przywara@arm.com>: This is remainder of the AXP717 fix series, containing support for the boost regulator. This is meant to increase the battery voltage to the 5 volts required to provide the USB VBUS power. It's the usual trinity of DT bindings patch (1/3), the MFD part describing the PMIC registers (2/3) and the final patch to model the regulator (3/3). Compared to v2, this drops the merged patches, and just retains the boost related parts. It also changes the internal name of the register to AXP717_MODULE_EN_CONTROL_2, since there is another control register we will need later for battery support.

There's still a bit of OF-specific code in the regulator device lookup function. Move those bits of code over to of_regulator.c, and create a new function of_regulator_dev_lookup() to encapsulate the code moved out of regulator_dev_lookup(). Also mark of_find_regulator_by_node() as static, since there are no other users in other compile units. There are no functional changes. A line alignment was also fixed. Signed-off-by:

of_regulator_bulk_get_all() has a comment section that pretty much resembles a kerneldoc block, except that the block begins with "/*" instead of "/**".

kernel-doc complains about missing "Return" section for the function regulator_irq_map_event_simple(). Add a "Return" section for it based on its behavior. The function actually always returns 0, but fills in fields in its @rid parameter as needed. Expand the description of the parameter to cover this. While at it fix a typo found in the description of the same function. Reported-by:

kernel-doc complains about missing "Return" section for many documented functions in the regulator core. Some with free-form return value descriptions have been fixed in the previous patch. The remaining are completely missing any mention of return values. Add "Return" sections to these kerneldoc blocks with basic descriptions. In a few cases where the functions don't call even more functions and the error numbers are known, those are documented in detail. Signed-off-by:
