isl1208_i2c_set_alarm() uses deprecated rtc_tm_to_time(),
which will overflow in year 2106 on 32-bit machines.This patch solves this by:
- Replacing rtc_tm_to_time() with rtc_tm_sub()Cc: Herbert Valerio Riedel

There're many sites need comparing the two rtc_time variants for many
rtc drivers, especially in the instances of rtc_class_ops::set_alarm().So add this common helper function to make things easy.

Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)//
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
e = devm_ioremap_resource(e1, res);

Return -EINVAL if the voltage low bit is set to avoid getting a bogus
time at boot.
There was a comment stating that util-linux hwclock refuses to set a
new time if we return an error code on read, but at least the current
version do set the time as expected. Remove the comment and the check
for valid time, and let the rtc core check it for us.Signed-off-by: Jan Kardell

When entering suspend while an wakeup alarm is set, enable_set_wake
should make sure that the RTC interrupt keep being enabled and the
.irq_set_wake for the RTC interrupt get called. However, since the
driver uses the suspend_noirq callback, the call to enable_irq_wake
has been made after disabling the interrupts. While .irq_set_wake
has been called properly, the interrupt remained disabled.Use the suspend callback to call enable_irq_wake early enough to
ensure the RTC interrupt remains enabled.Fixes: 7654e9d4fd8f ("drivers/rtc/rtc-snvs: fix suspend/resume")

Using gpio_request_array()/gpio_free_array() can make the code
simpler because it can set the direction and initial value
in one shot and the for loop is unnecessary.Also, struct v3020_gpio is removed, because the struct v3020_gpio
is replaced with struct gpio.Signed-off-by: Jingoo Han

According to C99, %2.s means 'print two spaces' (a precision of
. without following digits or * means 0). The kernel's printf
implementation, however, treats that case as if no precision was
given, but relying on that quirk is rather silly. Also, since no -
(aka left-justify) flag is given, the field with of 2 would then cause
the alarm->enabled case to come out as "o n". Deobfuscate it.Signed-off-by: Rasmus Villemoes
