Hi all,

After merging the hwmon-staging tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/hwmon/pmbus/isl68137.c: In function 'raa_dmpvr2_read_word_data':

Caused by commit

  96c72647bc37 ("hwmon: (pmbus) add support for 2nd Gen Renesas digital multiphase")

I have used the version of the hwmon-staging from next-20200320 for today.
