I agree. But, in this case, RTC device driver can not do anything. And if
rtc_suspend() returns a minus value, then suspend will be aborted. So,
in the worst case, suspend will be failed continually. I think this is not
good.
Most RTC device drivers don't verify the read time value. Even some drivers
just return '0' value(omap, tegra, ...). So, I think the higher level
framework like /drivers/rtc/interface.c should check and handle the rtc
read time.
