disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable because of requesting.

On the other hand, request_irq() after setting IRQ_NOAUTOEN as
below
irq_set_status_flags(irq, IRQ_NOAUTOEN);
request_irq(dev, irq...);
can also be replaced by request_irq() with IRQF_NO_AUTOEN flag.

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).

The driver handles wakeup irq correctly using device_init_wakeup and
enable_irq_wake. There's no need to use IRQF_NO_SUSPEND while registering
the interrupt.

This patch removes the use of IRQF_NO_SUSPEND flag.

Though the tegra-kbc driver should/will continue to support the legacy
"nvidia,wakeup-source" property to enable keyboard as the wakeup source,
we need to add support for the new standard property "wakeup-source".

This patch adds support for "wakeup-source" property in addition to the
existing "nvidia,wakeup-source" property.
