Temporary strings with volt_* file names should be released after the
debugfs entries are created.
The patch eliminates kmemleak reports with the following stack trace
(multiple objects depending on HW):
unreferenced object 0xcedbc5a0 (size 64):
comm "swapper", pid 1, jiffies 4294929375 (age 423.734s)
hex dump (first 32 bytes):
76 6f 6c 74 5f 39 37 35 30 30 30 00 00 00 00 00 volt_975000.....
