caff0cc419 rtc: ds1343: remove misuse of IRQF_NO_SUSPEND flag
The IRQF_NO_SUSPEND flag is used to identify the interrupts that should
be left enabled so as to allow them to work as expected during the
suspend-resume cycle, but doesn't guarantee that it will wake the system
from a suspended state, enable_irq_wake is recommended to be used for
the wakeup.

This patch removes the use of IRQF_NO_SUSPEND flags and uses newly
introduce PM wakeup APIs dev_pm_{set,clear}_wake_irq.

f4843b19d2 rtc: ds1343: clean up ds1343_nvram_read()/ds1343_nvram_write()
The change removes redundant sysfs binary file boundary checks, since
this task is already done on caller side in fs/sysfs/file.c

10b06b87b7 drivers/rtc/rtc-ds1343.c: fix potential race condition
Avoid the potential race condition by avoiding bailing out of driver in
probe after registering with rtc subsystem

Also the set_alarm , read_alarm and alarm_irq_enable returns error if irq
registration fails in probe.

Also the sysfs will not create entry for alarm if irq registration fails
in probe.
