track_chunk is always called with interrupts enabled. Consequently, we
do not need to save and restore interrupt state in "flags" variable.
This patch changes spin_lock_irqsave to spin_lock_irq and
spin_unlock_irqrestore to spin_unlock_irq.

hwmon: (w83627hf) Add support for suspend
On suspend some register values are lost, most notably the Value RAM
areas but also other limits. Restore them on resume. On top of that,
some fixups are needed to work around BIOS bugs, in particular when
the BIOS omits running the same initialization sequence on resume
that it does after boot. In that case we have to carry initialization
over suspend.

These got broken by recent patches fixing checkpatch warnings in these

driver core / PM: move the calling to device_pm_remove behind the calling to bus_remove_device
We hit an hang issue when removing a mmc device on Medfield Android phone by sysfs interface.
device_pm_remove will call pm_runtime_remove which would disable
runtime PM of the device. After that pm_runtime_get* or
pm_runtime_put* will be ignored. So if we disable the runtime PM
before device really be removed, drivers' _remove callback may
access HW even pm_runtime_get* fails. That is bad.
remove_dev might call pm_runtime_get_sync/put_sync.
Then, generic device_release_driver also calls pm_runtime_get_sync/put_sync.
Since device_del => device_pm_remove firstly, later _get_sync wouldn't really wake up the device.
I git log -p to find the patch which moves the calling to device_pm_remove ahead.
It's below patch:
This patch reorganizes the way suspend and resume notifications are
sent to drivers. The major changes are that now the PM core acquires
every device semaphore before calling the methods, and calls to
device_add() during suspends will fail, while calls to device_del()
during suspends will block.
It also provides a way to safely remove a suspended device with the
help of the PM core, by using the device_pm_schedule_removal() callback
introduced specifically for this purpose, and updates two drivers (msr
and cpuid) that need to use it.
As device_pm_schedule_removal is deleted by another patch, we need also revert other parts of the patch,
i.e. move the calling of device_pm_remove after the calling to bus_remove_device.
