commit 4d7a5644e4adfafe76c2bd8ee168e3f3b5dae3a8 upstream.
Add missing newline to dev_warn() message string. This is more of an issue
with older kernels that don't automatically add a newline if it was missing
from the end of the previous line.

commit 8d59582a867470a3e0c3eced4a01625ae8dc546b upstream.
An off-by-one error caused some inputs to not be created by the driver
when they should. TMP421 gets only one input instead of two, TMP422
gets two instead of three, etc. Fix the bug by listing explicitly the
number of inputs each device has.

commit 98ceb75c7c14eada76b0aa9f03a635a735cee3cb upstream.
Some code that is in ams_exit() (the module exit code) should instead
be called when the device (not module) is removed. It probably doesn't
make much of a difference in the PMU case, but in the I2C case it does
matter.
I make no guarantee that my fix isn't racy, I'm not familiar enough
with the ams driver code to tell for sure.

commit 85f8d3e5faea8bd36c3e5196f8334f7db45e19b2 upstream.
The #define ADT7462_VOLT_COUNT is wrong, it should be 13 not 12. All the
for loops that use this as a limit count are of the typical form, "for
(n = 0; n < ADT7462_VOLT_COUNT; n++)", so to loop through all voltages
w/o missing the last one it is necessary for the count to be one greater
than it is. (Specifically, you will miss the +1.5V 3GPIO input with count
= 12 vs. 13.)

commit 197027e6ef830d60e10f76efc8d12bf3b6c35db5 upstream.
Different motherboards have different PNP declarations for LM78/LM79
chips. Some declare the whole range of I/O ports (8 ports), some
declare only the useful ports (2 ports at offset 5) and some declare
fancy ranges, for example 4 ports at offset 4. To properly handle all
cases, request all ports individually for probing. After we have
determined that we really have an LM78 or LM79 chip, the useful port
range will be requested again, as a single block.
This fixes the driver on the Olivetti M3000 DT 540, at least.

commit 1fe63ab47a617ee95f562eaa7ddbbc59981ff8c6 upstream.
The max junction temperature of Atom N450/D410/D510 CPUs is 100 degrees
Celsius. Since these CPUs are always coupled with Intel NM10 chipset in
one package, the best way to verify whether an Atom CPU is N450/D410/D510
is to check the host bridge device.

responsible for updating the readings from the hwmon sensors) is disabled

under Linux, native drivers are locked out from ACPI owned resources so

There is no point in implementing a detect callback for the LTC4215
and LTC4245, as these devices can't be detected. It was there solely
to handle "force" module parameters to instantiate devices, but now
we have a better sysfs interface that can do the same.
So we can get rid of the ugly module parameters and the detect
callbacks. This shrinks the binary module sizes by 36% and 46%,
respectively.

Since this code path is never called with ix == 3 (the device has no PWM4

On resume from suspend, the driver currently resets the logical state as
if it was brought up from halt. This patch uses the
dev_pm_ops.resume/restore methods to synchronize the hardware with the
memorized logical state, in effect bringing back the accelerometer and
backlight to the state prior to suspend. Works for both suspend to ram

The ADM1023 temperature sensor supports higher resolution for its external
sensor (sensitivity of 1/8 deg C). This patch makes this higher

This offers a way for platforms to define flags and thresholds for the
