The unicore32 port is removed from the kernel.
There is no point to keep stale RTC driver for this architecture.

The RTC core now has error messages in case of registration failure, there
is no need to have other messages in the drivers.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>
@@
expression ret;
struct platform_device *E;
@@
ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);
if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>
While we're here, remove braces on if statements that only have one
statement (manually).

Currently, the driver unregisters the IRQs when the rtc character device is
closed. This means that the device needs to stay open to get alarms while
the usual use case will open the device, set the alarm and close the
device.
Move the IRQ requests to puv3_rtc_probe() and use the devm managed versions
so we don't need to free them.

Because dev_*() are used along with pr_debug() function in this code, the
debug message is not tidy. This patch converts from pr_debug() to
dev_dbg() since dev_*() are encouraged to use in device driver code.

The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
= NULL when no driver is bound"). Thus, it is not needed to manually
clear the device driver data to NULL.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

The patch renames puv3_rtcdrv to puv3_rtc_driver, so that modpost will know
that this is simply a list of pointers to driver functions, in which case
the section mismatch is OK. (Thanks Michal Marek)

This patch converts the driver to use the module_platform_driver()
macro which makes the code smaller and a bit simpler.

Several fixes as well where the +1 was missing.
Done via coccinelle scripts like:
@@
struct resource *ptr;
@@
- ptr->end - ptr->start + 1
+ resource_size(ptr)
and some grep and typing.
Mostly uncompiled, no cross-compilers.

The patch moves rtc driver for PKUnity-v3 SoC from arch/unicore32/kernel/
