  ext4: BUG_ON fix: check if page has buffers before calling page_buffers()

The iTCO_wdt driver erroneously releases the pci_dev, and causes PCI hotremove
to fail because of an incorrect usage count.

The probe for this driver does a for_each_pci_dev() which gets a reference for
a pci_dev when iTCO_wdt_init() is successful.  The for_each_pci_dev() loop
puts a reference for a pci_dev when iTCO_wdt_init() fails, so the
iTCO_wdt_init() does not need to do any pci_dev_put()'s.

The only pci_dev_put() that is required is in the iTCO_wdt_cleanup() function.

I have a regulator A that sets regulator B as its supply. When I call
set_supply to add B as the supply for A, regulator A gets added to the
supply_list for regulator B.

When I call regulator_disable(A), I end up with a call chain like this:

regulator_disable(A)
> mutex_lock(A)
> _regulator_disable(A)
>> _regulator_disable(B)
>>> _notifier_call_chain(B)
>>>> mutex_lock(A)

Which results in dead lock since we are trying to acquire the mutex lock
for regulator A which we already hold.

This patch addresses this issue by moving the call to disable regulator
B outside of the lock aquired inside the initial call to
regulator_disable.

This change also addresses the issue of not acquiring the mutex for
regulator B before calling _regulator_disable(B).

Allow machine drivers to explicitly enable the use of the dummy regulator,
enabling simpler support for systems with only a few specific supplies
visible to software.

It is strongly recommended that this is not used on systems with
substantial software control over their PMICs, for maximum functionality
constrints should be as fully specified as possible.

MAX8952 PMIC is used to provide voltage output between 770mV - 1400mV
with DVS support. In this initial release, users can set voltages for
four DVS modes, RAMP delay values, and SYNC frequency.
Controlling FPWM/SYNC_MODE/Pull-Down/Ramp Modes and reading CHIP_ID
is not supported in this release.

If GPIO of EN is not valid in platform data, the driver assumes that it
is always-on. If GPIO of VID0 or VID1 is invalid, the driver pulls down
VID0 and VID1 to fix DVS mode as 0 and disables DVS support.

We assume that V_OUT is capable to provide every voltage from 770mV to
1.40V in 10mV steps although the data sheet has some ambiguity on it.

Add support for the IT8721F/IT8758E. These new chips differ from the

* PWM values are 8-bit instead of 7-bit.
There are other minor changes we don't have to care about in the

Another change is that we will handle internal voltage scaling in the
driver instead of delegating the work to user-space.
