Andy Shevchenko a3f60bb35f rtc: rx6110: Switch to use %ptR
Use %ptR instead of open coded variant to print content of
struct rtc_time in human readable format.

Alexandre Belloni 22652ba724 rtc: stop validating rtc_time in .read_time
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.

Julia Lawall 34c7b3ac4c rtc: constify rtc_class_ops structures
Check for rtc_class_ops structures that are only passed to
devm_rtc_device_register, rtc_device_register,
platform_device_register_data, all of which declare the corresponding
parameter as const.  Declare rtc_class_ops structures that have these
properties as const.

The semantic patch that makes this change is as follows:

Steffen Trumtrar 68298c2dac rtc: add driver for RX6110SA real time clock
The RX6110 comes in two different variants: SPI and I2C.
This driver only supports the SPI variant.

If the need ever arises to also support the I2C variant, this driver
could easily be refactored to support both cases.
