commit abd6633c67925f90775bb74755f9c547e30f1f20 ("pnp: add a shutdown
method to pnp drivers") adds shutdown method to bus driver blindly. With
it, driver->shutdown is no longer valid.Use pnp_driver->shutdown instead.

RTC core won't allow wakeup alarms to be set if RTC devices' parent (i.e.
i2c_client or spi_device) isn't wakeup capable.For I2C devices there is I2C_CLIENT_WAKE flag exists that we can pass via
board info, and if set, I2C core will initialize wakeup capability. For
SPI devices there is no such flag at all.I believe that it's not platform code responsibility to allow or disallow
wakeups, instead, drivers themselves should set the capability if a device
can trigger wakeups.That's what drivers/base/power/sysfs.c says:
* It is the responsibility of device drivers to enable (or disable)
* wakeup signaling as part of changing device power states, respecting
* the policy choices provided through the driver model.I2C and SPI RTC devices send wakeup events via interrupt lines, so we
should set the wakeup capability if IRQ is routed.Ideally we should also check irq for wakeup capability before setting
device's capability, i.e.if (can_irq_wake(irq))
device_set_wakeup_capable(&client->dev, 1);But there is no can_irq_wake() call exist, and it is not that trivial to
implement it for all interrupts controllers and complex/cascaded setups.drivers/base/power/sysfs.c also covers these cases:
* Devices may not be able to generate wakeup events from all power
* states. Also, the events may be ignored in some configurations;
* for example, they might need help from other devices that aren't
* activeSo there is no guarantee that wakeup will actually work, and so I think
there is no point in being pedantic wrt checking IRQ wakeup capability.Signed-off-by: Anton Vorontsov

- Call dev_set_drvdata before rtc device creation.
- Use its own spinlock instead of rtc->irq_lock. Because pdata->rtc
must be initialized to use the irq_lock (pdata->rtc->irq_lock). There
is a small window which rtc methods can be called before pdata->rtc is
initialized.And there is no need use the irq_lock to protect hardware registers.
The driver's own spinlock shoule be enough.- Check pdata->rtc before calling rtc_update_irq.
- Use alarm_irq_enable and remove ioctl routine.
- Use devres APIs and simplify error/remove path.

I noticed that rtc wont generate interrupts after a resume from disk.
Here hpet rtc emulation is used.Problem is that rtc hpet comparator, isn't reinitialized after resume.
Easiest way to solve this, is always mask all hpet interrupts on suspend
This is triggered, when suspending with alarm set.Otherwise, hpet driver will think it doesn't need to reinitialize
the rtc comparator, thus rtc interrupts won't work.This emulation isn't need for wakealarm.

Bring the WM8350 IRQ API more in line with the generic IRQ API by
masking and unmasking interrupts as they are requested and freed.
This is mostly just a case of deleting the mask and unmask calls
from the individual drivers.The RTC driver is changed to mask the periodic IRQ after requesting
it rather than only unmasking the alarm IRQ. If the periodic IRQ
fires in the period where it is reqested then there will be a
spurious notification but there should be no serious consequences
from this.The CODEC drive is changed to explicitly disable headphone jack
detection prior to requesting the IRQs. This will avoid the IRQ
firing with no jack set up.Signed-off-by: Mark Brown

Since platform_device_add_data copies the passed data, the allocated
subdev_pdata is never freed. A simple fix would be to either free subdev_pdata
or put it onto the stack. But since the pcf50633 child devices can rely on
beeing children of the pcf50633 core device it's much more elegant to get access
to pcf50633 core structure through that link. This allows to get completly rid
of pcf5033_subdev_pdata.Signed-off-by: Lars-Peter Clausen
