rtc: m41t80: avoid out of range year values

2016-03-18T23:00:59+00:00

Avoid saving an out of range year value to the RTC. Reading that value from the RTC again returns a totally wrong time value. For Example $ timedatectl set-ntp no $ timedatectl set-time "1990-01-01 12:12:00" # Reboot rtc-m41t80 0-0068: setting system clock to 2090-01-01 12:12:35 UTC (3786955955) Signed-off-by: Stefan Christ Signed-off-by: Alexandre Belloni

drivers/rtc/rtc-m41t80.c: clean up error paths

2014-06-06T23:08:07+00:00

There is no cleanup needed when something fails in probe, so no need for goto. Directly return when something fails. Signed-off-by: Wolfram Sang Cc: Jingoo Han Acked-by: Alessandro Zummo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-m41t80.c: remove DRV_VERSION macro

2014-06-06T23:08:07+00:00

History is in git, no need for sperate versioning. Also remove the success printout, RTC core does it, too. Signed-off-by: Wolfram Sang Cc: Jingoo Han Cc: Alessandro Zummo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-m41t80.c: remove disabled alarm functionality

2012-10-05T18:05:07+00:00

Commit c3b79770e51a ("rtc: m41t80: Workaround broken alarm functionality") disabled m41t80's alarm functions. But since those functions were not touched, building this driver triggers these GCC warnings: drivers/rtc/rtc-m41t80.c:216:12: warning: 'm41t80_rtc_alarm_irq_enable' defined but not used [-Wunused-function] drivers/rtc/rtc-m41t80.c:238:12: warning: 'm41t80_rtc_set_alarm' defined but not used [-Wunused-function] drivers/rtc/rtc-m41t80.c:308:12: warning: 'm41t80_rtc_read_alarm' defined but not used [-Wunused-function] Remove these functions (and the commented out references to them) to silence these warnings. Anyone wanting to fix the alarm irq functionality can easily find the removed code in the git log of this file or through some web searches.
