power_supply_property_is_writeable() gets called from the is_visible() callback for the sysfs attributes of power_supply class devices and for the sysfs attributes of power_supply core instantiated hwmon class devices. These sysfs attributes get registered by the device_add() respectively power_supply_add_hwmon_sysfs() calls in power_supply_register(). use_cnt gets initialized to 0 and is incremented only after these calls. So when power_supply_property_is_writeable() gets called it always return -ENODEV because of use_cnt == 0. This causes all the attributes to have permissions of 444 even those which should be writable. This used to be a problem only for hwmon sysfs attributes but since commit |

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 reStructuredText 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.
