Here is a patchset, is it visible in your mailbox?
If so, please pull it into your tree.

> Summary of what this patchset does:
>
> Our board has 4 DS18B20 1-wire temperature sensors. Each 1-wire bus and the
> sensor under it is already configured against the Linux 1-wire driver
> (called w1). They have a sysfs file(e.g.
> /sys/bus/w1/devices/w1_bus_master1/28-000007704f4c/w1_slave) which, when read,
> runs code to read the temperature. We'd like the temperatures to show up in
> hwmon, so that the BMC IPMI sensor plumbing can forward those to host.
