There is only one ds2404_chip_ops struct that is implemented, remove the
unnecessary indirection.

The real-time clock is a 5-byte binary counter. It is incremented 256 times
per second. The least significant byte is a count of fractional seconds.
The upper four bytes are a count of seconds. The realtime clock can
accumulate 136 years of seconds before rolling over.

rtc: stop validating rtc_time in .read_time2018-03-02T09:09:58+00:00Alexandre Bellonialexandre.belloni@bootlin.com2018-02-19T15:23:56+00:00urn:sha1:22652ba72453d35c8a637d5c0f06b3dc29ff9eb0
The RTC core is always calling rtc_valid_tm after the read_time callback.
It is not necessary to call it just before returning from the callback.

driver core.
