3.16.84-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Paul Kocialkowski paul.kocialkowski@bootlin.com
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.
