[PATCH 2/2] regulator: use consumer->supply_name in debugfs/regulator_summary

[Michał Mirosław]

Before:

 regulator                      ena use open bypass voltage current min     max
-----------------------------------------------------------------------------------
 regulator-dummy                  1   0    2      0     0mV     0mA 0mV     0mV
    1-0010                                                          0mV     0mV
    1-0010                                                          0mV     0mV

After:

 regulator                      ena use open bypass voltage current min     max
