RTC wakealarm file is missing in v6.1-rc1

In the v6.1-rc1 kernel release from about 24 hours ago, the wakealarm file for the real time clock appears to be missing. Specifically:

/sys/class/rtc/rtc0/wakealarm

Without this sysfs file, the rtcwake and sleepgraph tools no longer function properly (and probably all tools that use the RTC through sysfs). I've tested on 10 machines so far and this occurs on all of them regardless of the specific hardware.

The issue is in this patch set for the rtc subsystem. If I remove this commit and rebuild, the issue goes away. I'm in the process of bisecting further.

I've opened a bugzilla issue here:
https://bugzilla.kernel.org/show_bug.cgi?id=216600

I've bisected this issue to a single commit. I recommend that this commit be reverted immediately while Raphael creates a fix. It breaks linux tools that use the rtc wakealarm.
