3.16.84-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Paul Kocialkowski <paul.kocialkowski@xxxxxxxxxxx>
commit f236a2a2ebabad0848ad0995af7ad1dc7029e895 upstream.
The current code returns -EPERM when the voltage loss bit is set.
Since the bit indicates that the time value is not valid, return
-EINVAL instead, which is the appropriate error code for this
situation.
