If our timestamp here wasn\u0027t the same (minutes and higher) as what\nwas used internally there, then we might end up populating the -1 fields\nwith inconsistent values.\n\nThis fixes readbacks from /sys/class/rtc/rtc?/wakealarm, as well as other\ncode paths which call rtc_read_alarm().\n\nSigned-off-by: Mark Lord \u003cmlord@pobox.com\u003e\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nCc: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "97144c67566241db46633727f2860e6428373fe4", "tree": "b3863ed198037668cb80df710678a6e249842654", "parents": [ "d691eb901e044065de10756ea78a5758d457c7fd" ], "author": { "name": "David Brownell", "email": "david-b@pacbell.net", "time": "Tue Oct 16 01:28:16 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:43:13 2007 -0700" }, "message": "rtc_irq_set_freq() requires power-of-two and associated kerneldoc\n\nRTC periodic IRQs are only defined to work for 2^N Hz values.
