From: Paul Kocialkowski <paul.kocialkowski@bootlin.com>
[ Upstream commit f236a2a2ebabad0848ad0995af7ad1dc7029e895 ]
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.
