+Subject: [PATCH hwmon] hwmon: (pmbus) Fix driver info initialization in probe
+ routine
+
+Fix tps53679_probe() by using dynamically allocated ?pmbus_driver_info?
+structure instead of static. Usage of static structures causes
+overwritten of the field ?vrm_version? - when the number of tps53679
+devices with the different ?vrm_version? are used within the same
+system, the last probed device overwrites this field for all others.
+
+Fixes: 610526527a13e4c9 ("hwmon: (pmbus) Add support for Texas Instruments tps53679 device")
