commita64a7e8a0bupstream. pmbus_notify() calls sysfs_notify() and kobject_uevent() on the i2c client's kobject, but the alarm attributes live on the hwmon class device registered by pmbus_do_probe(). Notifying the parent i2c device is a no-op for both poll(POLLPRI) waiters and udev listeners: the named attribute does not exist on that kobject. Notify the hwmon device instead, so poll() wakes up and "change" uevents fire on the inX_alarm/tempX_alarm attributes when SMBALERT# reports a fault.

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.
