Commit 2265cef2 (hwmon: (w83627ehf) Properly report PECI and AMD-SI
sensor types) results in kernel panic if data->temp_label was not
initialized.
The problem was found with chip W83627DHG-P.Add check if data->temp->label was set before use.
Based on incomplete patch by Alexander Beregalov.

The definition of TO_ATTR_NO in the non-SMP case is wrong. As the SMP
definition resolves to the correct value, just use this for both
cases.Without this fix the temperature attributes are named temp0_* instead
of temp2_*, so libsensors won't pick them. Broken since kernel 3.0.Signed-off-by: Jean Delvare

This is essentially a stripped down version of the W83627DHG. Noticeable
difference is that it is still powered with +5V, as older models, even
though the ADC resolution is 8 mV as newer models have.Thanks to Ulf Bruman (Saab Group) for doing all the testing.

The probe function has grown pretty large, I think it's time for some
cleanups, starting with these two simple ones:
* Move temp3/in6 check for the W83667HG later in the function, where
it is done for all other chip types.
* Move temperature register setting to a separate function, to avoid
code duplication.Signed-off-by: Jean Delvare

When temperature sources are PECI or AMD-SI agents, it makes no sense
to report their type as diode or thermistor. Instead we must report

Clean up the code to make it more readable:
* Remove reg_ and new_ prefixes from variable names, they made the
names longer, causing extra line breaks, while not adding much
value.
* Introduce struct device dev* = &client->dev in two functions, to
avoid repeating client->dev everywhere in these functions.Signed-off-by: Jean Delvare

With some configuration option combinations, we get the following

drivers/hwmon/lm90.c:1187: warning: 'reg_status2' may be used
uninitialized in this functionWe can solve these easily by reading the register values first and
checking for errors later. These errors should be very rare, even in
the case of failed detection, so this change has no impact on
performance. And this makes checkpatch.pl happier.Reported-by: Guenter Roeck

I am under the impression that error paths in functions
aem_init_aem1_inst() and aem_init_aem2_inst() are incorrect. In
several cases, the function returns 0 on error, which I suspect is
not intended. Fix this by properly tracking error codes.Signed-off-by: Jean Delvare

Always call _pmbus_read_byte() instead of pmbus_read_byte() in PMBus core
driver. With this change, device specific read functions can be implemented for
all registers.Since the device specific read_byte function is now always called, we need to be
more careful with page validations. Only fail if the passed page number is larger
than 0, since -1 means "current page".Signed-off-by: Guenter Roeck

Before this patch the f71882fg driver completely fails to initialize
on systems which have reserved settings in the pwm enable register, and
it disables all auto pwm sysfs attributes if any fan is controlled by
a digital sensor reading.This patch changes the fail to initialize into don't register any attributes
for the fan for which there are reserved settings in the pwm enable register
and also makes the not registering of auto pwm sysfs attributes a per fan

Since commit [c58543c8: genirq: Run irq handlers with interrupts disabled],
we run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).So now this flag is a NOOP and can be removed.
