Hi all,

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

WARNING: modpost: module dps920ab uses symbol pmbus_get_debugfs_dir from namespace PMBUS, but does not import it.
WARNING: modpost: module dps920ab uses symbol pmbus_do_probe from namespace PMBUS, but does not import it.

WARNING: modpost: module dps920ab uses symbol pmbus_write_word_data from namespace PMBUS, but does not import it.
