From 626fea046b49490cdd8c917911437737c1f904a8 Mon Sep 17 00:00:00 2001 From: Xunlei Pang Date: Fri, 12 Jun 2015 10:04:09 +0800 Subject: rtc: pcf8563: Replace deprecated rtc_time_to_tm() and rtc_tm_to_time() pcf8563_rtc_set_alarm() uses deprecated rtc_tm_to_time() and rtc_time_to_tm(), which will overflow in year 2106 on 32-bit machines. This patch solves this by: - Replacing rtc_time_to_tm() with rtc_time64_to_tm() - Replacing rtc_tm_to_time() with rtc_tm_to_time64() Acked-by: Arnd Bergmann Signed-off-by: Xunlei Pang Signed-off-by: Alexandre Belloni --- drivers/rtc/rtc-pcf8563.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'drivers/rtc') diff --git a/drivers/rtc/rtc-pcf8563.c b/drivers/rtc/rtc-pcf8563.c index 229426dee1ea..fc564d359941 100644 --- a/drivers/rtc/rtc-pcf8563.c +++ b/drivers/rtc/rtc-pcf8563.c @@ -358,13 +358,13 @@ static int pcf8563_rtc_set_alarm(struct device *dev, struct rtc_wkalrm *tm) struct i2c_client *client = to_i2c_client(dev); unsigned char buf[4]; int err; - unsigned long alarm_time; /* The alarm has no seconds, round up to nearest minute */ if (tm->time.tm_sec) { - rtc_tm_to_time(&tm->time, &alarm_time); - alarm_time += 60-tm->time.tm_sec; - rtc_time_to_tm(alarm_time, &tm->time); + time64_t alarm_time = rtc_tm_to_time64(&tm->time); + + alarm_time += 60 - tm->time.tm_sec; + rtc_time64_to_tm(alarm_time, &tm->time); } dev_dbg(dev, "%s, min=%d hour=%d wday=%d mday=%d " -- cgit v1.2.3-59-g8ed1b
