Pull RTC updates from Alexandre Belloni: "More cleanup this cycle, with the final goal of removing the rtc_time_to_tm and rtc_tm_to_time wrappers. All the drivers that have been modified for this now are ready for the end of times (whether it happens in 2033, 2038, 2106, 2127 or even 4052). There is also a single new driver and the usual fixes and features. Summary: Subsystem: - The rtc_time_to_tm and rtc_tm_to_time wrappers have finally been removed and only the 64bit version remain. - hctosys now works with drivers compiled as modules New driver: - MediaTek MT2712 SoC based RTC Drivers: - set range for 88pm860x, au1xxx, cpcap, da9052, davinci, ds1305, ds1374, mcp5121, pl030, pl031, pm8xxx, puv3, sa1100, sirfsoc, starfire, sun6i - ds1307: DS1388 oscillator failure detection and watchdog support - jz4740: JZ4760 support - pcf85063: clock out pin support - sun6i: external 32k oscillator is now optional, the range is now handled by the core, providing a solution for 2034" * tag 'rtc-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (87 commits) rtc: ds1307: check for failed memory allocation on wdt rtc: class: remove redundant assignment to variable err rtc: remove rtc_time_to_tm and rtc_tm_to_time rtc: sun6i: let the core handle rtc range rtc: sun6i: switch to rtc_time64_to_tm/rtc_tm_to_time64 rtc: ds1307: add support for watchdog timer on ds1388 rtc: da9052: switch to rtc_time64_to_tm/rtc_tm_to_time64 rtc: da9052: set range rtc: da9052: convert to devm_rtc_allocate_device rtc: imx-sc: Align imx sc msg structs to 4 rtc: fsl-ftm-alarm: report alarm to core rtc: pcf85063: Add pcf85063 clkout control to common clock framework rtc: make definitions in include/uapi/linux/rtc.h actually useful for user space rtc: class: avoid unnecessary lookup in hctosys dt-bindings: rtc: Convert and update jz4740-rtc doc to YAML rtc: jz4740: Rename vendor-specific DT properties rtc: jz4740: Add support for JZ4760 SoC rtc: class: support hctosys from modular RTC drivers rtc: pm8xxx: clear alarm register when alarm is not enabled rtc: omap: drop unused dt-bindings header ...

rtc: ds1307: check for failed memory allocation on wdt

2020-04-03T11:38:24Z

Currently a failed memory allocation will lead to a null pointer dereference on point wdt. Fix this by checking for a failed allocation and just returning.

rtc: class: remove redundant assignment to variable err

2020-04-02T16:47:30Z

The variable err is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.
