## Overview

In the Linux kernel, the following vulnerability has been resolved:

misc: ad525x_dpot: use driver core groups for sysfs files

ad_dpot_probe() creates per-RDAC sysfs files manually and then
optionally creates the command sysfs group. This leaves probe responsible
for rolling back partial sysfs state and makes remove responsible for
matching every file that probe created.

Move the device attributes into driver core dev_groups for the I2C and
SPI drivers and use an is_visible() callback to expose only the
attributes supported by the probed device. With this shape, the driver
core creates the sysfs files only after probe succeeds and removes them
before the remove callback frees the driver data.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
