CVE-2026-98199

hwmon: (pmbus/core) increase number of phases and add new mask

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

hwmon: (pmbus/core) increase number of phases and add new mask

Increase the number of phases to 16 as a new upcoming device supports
such a number.

While at it, add a new mask for controlling the source of the output
voltage.

Note (groeck):

This patch was meant to prepare for support of MAX20826 and compatible
devices, which support more than 10 phases per page. However, Sashiko
reports that the mp2975 driver already supports up to 14 phases, and the
mp2856 driver supports up to 12 phases. This already has the potential for
out-of-bounds writes when probing the affected chips, making this patch a
bug fix.
