In case of error, we return 0.
This is spurious and not consistent with the other functions of the driver.
Commit 22652ba72453 has modified more than what is said in the commit
message and error should be propagated.

Fixes: 22652ba72453 ("rtc: stop validating rtc_time in .read_time")
Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

Not sure that the Fixes tag is the right one.
It is related, but not 100% accurate IMHO.

Well, as you note, this make your commit message wrong 22652ba72453
didn't modified more than what it said and the behavior stayed exactly
the same as the previous one. Can you reword?
