Wait. The message says that "2000 will be assumed" which is not an
error. The message indicates that driver will proceed, thus the warning.
However the driver won't proceed because the max77686_rtc_set_time()
will abort. This came from max8997 which has the same issue.
This means that either message should be changed (dev_err() without the
"assume" verb) or the function should not abort and set the year to
2000+something (then dev_warn()... look at rtc-ds3234.c and rtc-mcp795.c).
The easiest would be to choose #1 - no changes in the logic.
