20005cc58d hwmon: (max6650) Allow fan shutdown and initial rpm target
The fan can be stopped by writing "3" to pwm1_enable in sysfs.

Add devicetree property for early initialization of the fan controller
to prevent overheating, for example when resetting the board while the
fan was completely turned off.

Also improve error reporting, I2C failures were ignored while writing
new values.

fc72af3ad4 hwmon: (nct6775) Do not accept force_id unless chip is found
Since commit 698a7c24a5 ("hwmon: (nct6775) Support two SuperIO chips
in the same system"), the driver supports two Super-IO chips. This has
the undesirable side effect that force_id always detects a second chip
at address 0xfff8, even if no chip exists at that address.

nct6775: Found NCT6793D or compatible chip at 0x4e:0xfff8

If no chip at all is found at a given SIO address, it does not make sense
to instantiate it. Limit force_id to only work if some chip is found,
that is if the chip ID returns a value other than 0xffff.

d560168b5d hwmon: (core) New hwmon registration API
Up to now, each hwmon driver has to implement its own sysfs attributes.
This requires a lot of template code, and distracts from the driver's core
function to read and write chip registers.

To be able to reduce driver complexity, move sensor attribute handling
and thermal zone registration into hwmon core. By using the new API,
driver code and data size is typically reduced by 20-70%, depending
on driver complexity and the number of sysfs attributes supported.

With this patch, the new API only supports thermal sensors. Support for
other sensor types will be added with subsequent patches.

f48ccb26e2 hwmon: (lm95241) Fix overflow problems, write conversion rate to chip
Writing the update_interval attribute could result in an overflow if
a number close to the maximum unsigned long was written. At the same
time, even though the chip supports setting the conversion rate,
the selected conversion rate was not actually written to the chip.

Fix the second problem by selecting valid (supported) conversion rates,
and writing the selected conversion rate to the chip. This also fixes the
first problem, since arbitrary conversion rates are now converted to
actually supported conversion rates.

Also, set the default chip conversion rate to 1 second. Previously, the
chip was configured for continuous conversion, but readings were only
retrieved every seond, which doesn't make much sense. If we only read a
value from the chip every second, we can as well save some power and only
convert in one-second intervals.

3e423945ea devpts: return NULL pts 'priv' entry for non-devpts nodes
In commit 8ead9dd547 ("devpts: more pty driver interface cleanups") I
made devpts_get_priv() just return the dentry->fs_data directly.  And
because I thought it wouldn't happen, I added a warning if you ever saw
a pts node that wasn't on devpts.

And no, that warning never triggered under any actual real use, but you
can trigger it by creating nonsensical pts nodes by hand.

So just revert the warning, and make devpts_get_priv() return NULL for
that case like it used to.
