Commit 7cc97d77ee has introduced a call to 'regulator_disable()' in the
.remove function.
So we should also have such a call in the .probe function in case of
error after a successful 'regulator_enable()' call.
Add a new label for that and use it.

If 'devm_regulator_get()' fails, we should go through the existing error
handling path instead of returning directly, as done is all the other
error handling paths in this function.

MADC[3:6] reads incorrect values without these two following changes:
- enable the 3v1 bias regulator for ADC[3:6]
- configure ADC[3:6] lines as input, not as USB

* Fix a regression in hid sensors suspend time as a result of adding runtime
pm. The normal flow of waking up devices in order to go into suspend
(given the devices are normally suspended when not reading) to a regression
in suspend time on some laptops (reports of an additional 8 seconds).
Fix this by checking to see if a user action resulting in the wake up, and
make it a null operation if it didn't. Note that for hid sensors, there is
nothing useful to be done when moving into a full suspend from a runtime
suspend so they might as well be left alone.
* rochip_saradc: fix some missing MODULE_* data including the licence so that
the driver does not taint the kernel incorrectly and can build as a module.
* twl4030 - mark irq as oneshot as it always should have been.
* inv-mpu - write formats for attributes not specified, leading to miss
interpretation of the gyro scale channel when written.
* Proximity ABI clarification. This had snuck through as a mess. Some
drivers thought proximity went in one direction, some the other. We went
with the most common option, documented it and fixed up the drivers going
the other way. Fix for sx9500 included in this set.
* ad624r - fix a wrong shift in the output data.
* at91_adc - remove a false limit on the value of the STARTUP register
applied by too small a type for the device tree parameter.
* cm3323 - clear the bits when setting the integration time (otherwise
we can only ever set more bits in the relevant field).
* bmc150-accel - multiple triggers are registered, but on error were not being
unwound in the opposite order leading to removal of triggers that had not
yet successfully been registered (count down instead of up when unwinding).
* tcs3414 - ensure right part of val / val2 pair read so that the integration
time is not always 0.
* cc10001_adc - bug in kconfig dependency. Use of OR when AND was intended.

Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests")
threaded IRQs without a primary handler need to be requested with
IRQF_ONESHOT, otherwise the request will fail.
So pass the IRQF_ONESHOT flag in this case.
The semantic patch that makes this change is available
in scripts/coccinelle/misc/irqf_oneshot.cocci.

The bit mask to read the setting of the constant current source
for measuring the NTC voltage was the wrong one. Since default
value is initialized to the lowest level (000 = 10uA) the difference
was probably never noticed in practice.

Not setting the raw parameter in the request causes it to be randomly
initialized to a value that might be different from zero or zero. This leads to
values that are randomly either raw or processed, making it very difficult to
make reliable use of the values.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.
