hwmon: (pmbus) Export pmbus device debugfs directory entry
Pmbus client drivers, if they want to use debugfs, should use the same root directory as the pmbus debugfs entries are using. Therefore, export the device dentry for the pmbus client. Signed-off-by: Edward A. James <eajames@us.ibm.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
