With the introduction of the HWMON compatibility layer to the power
supply framework in Linux 5.3, all power supply devices' names can be
used directly to create HWMON devices with the same names.
But HWMON has rules on allowable names that are different from those
used in the power supply framework. The dash character is forbidden, as
it is used by the libsensors library in userspace as a separator,
whereas this character is used in the device names in more than half of
the existing power supply drivers. This last case is consistent with the
typical naming usage with MFD and Device Tree.
This leads to warnings in the kernel log, with the format:
power_supply gpio-charger: hwmon: \
'gpio-charger' is not a valid name attribute, please fix
Add a protection to power_supply_add_hwmon_sysfs() that replaces any
dash in the device name with an underscore when registering with the
HWMON framework. Other forbidden characters (star, slash, space, tab,
newline) are not replaced, as they are not in common use.

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.
