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):
