staging: lustre: refactor libcfs initialization.
Many lustre modules depend on libcfs having initialized
properly, but do not explicit check that it did.
When lustre is built as discrete modules, this does not
cause a problem because if the libcfs module fails
initialization, the other modules don't even get loaded.
When lustre is compiled into the kernel, all module_init()
routines get run, so they need to check the required initialization
succeeded.
This patch splits out the initialization of libcfs into a new
libcfs_setup(), and has all modules call that.
The misc_register() call is kept separate as it does not allocate any
resources and if it fails, it fails hard - no point in retrying.
Other set-up allocates resources and so is best delayed until they
are needed, and can be worth retrying.
Ideally, the initialization would happen at mount time (or similar)
rather than at load time. Doing this requires each module to
check dependencies when they are activated rather than when
they are loaded. Achieving that is a much larger job that would
have to progress in stages.
For now, this change ensures that if some initialization in libcfs
fails, other modules will fail-safe.

Jonathan writes:
Second set of new device support, features and cleanup for IIO in the 4.18 cycle
Usual mixture of new devices support and other stuff. A couple of
staging graduations in here and some old driver drops.
New device support
* ad5686
- Add support for AD5691R, AD5692R, AD5693 and AD5693R i2c DACs
- Add support for AD5681R, AD5682R, AD5683 and AD5683R SPI DACs
* lmp91000
- Add ID for LMP91002
* stm32-dfsdm
- Add support for the stm32mp1 devices.
Drivers dropped
* ADE7753
- No longer easily available, no users came forward and needs a lot
of work to move out of staging.
* ADE7754
* ADE7758
* ADE7759
Staging graduations
- ad2s1200 - good cleanup from David Veenstra.
- tsl2772 (was tsl2x7x) - Brian's quest is at an end and
staging/iio/light is no more!
Features
* tools
- loop forever on a negative number of loops being specified.
* ltc 2632
- add of_match_table
- support an external reference regulator.
* mag3110
- Support continuous mode when running fast as it increases the
posssible sampling rate.
* ti-ads8688
- Add trigger and buffer support to this ADC.
Cleanups / minor tweaks.
* tools
- tidy up types in iio_generic_buffer.
* ad2s1200
- Whitespace cleanup.
- Drop pointless initializations.
- Improve kernel docs.
- Reorder to setup the SPI prior to device registration (race fix).
- Change to modern gpiod framework.
- Drop platform data and move to DT bindings. There are no in
kernel users of the platform data. Any out of tree boards will
need changes.
- Add an explicit compatible table.
- Provide _scale for angular velocity and angle channels.
- Add David Veenstra to copyright notice as this cleanup was non
trivial.
* ade8366
- Avoid a race by ensuring channel init is before registration
with the subsystem.
* afe
- binding spelling fix.
* imx7d-adc
- typo fix in Freescale
* inv_mpu6050
- tidy up an ugly loop to take advantage of known entry condition.
- add a comment explaining why the sensible sampling frequencies
are more limited than might be immediately apparent (aliasing).
* mma8452
- reduce the sleep time on data not ready when running at high
frequency.
* stm32-dfsdm
- add missing header.
* tsl2583
- fix integration_time_availabe which was in microsecs rather the
millisecs.
* tsl2x7x/tsl2772
- Whitespace cleanup.
- Change to direct returns where sensible.
- Turn the chip off in the registration error path.
- Use macro to reduce repition when setting up the device_info
structures.
- Change the _available attributes over to read_avail callback,
and the range definitions that supports.
- Fix some wrong period values.
- Add some range checkign for _write_raw.
- Rename the driver to tsl2772 to avoid wild card clash problems
in future.

iio: imu: inv_mpu6050: add comment about frequencies
Although the driver allows frequencies between 4 and 1000 Hz, only the
frequencies advertised in the available frequencies file are backed
properly by a low-pass filter to prevent aliasing, so it's best to use
them. Since this is not obvious to the user, add a comment explaining
what's going on.

Add support for specifying a negative -c option, meaning that we should

These devices are similar to AD5691R/AD5692R/AD5693/AD5693R except

* they use the SPI interface instead of I2C
* in the write control register, DB18 and DB17 are used for setting the
power mode, while DB16 is the REF bit. This is why a new regmap type
was defined and checked accordingly.
* the shift register is 24 bits wide, the first four bits are the command
bits followed by the data bits. As the data comprises of 20-bit, 18-bit
or 16-bit input code, this means that 4 LSB bits are don't care. This is
why the data needs to be shifted on the left with four bits. Therefore,
AD5683_REGMAP is checked inside a switch case in the ad5686_spi_write()
function. On the other hand, similar devices such as AD5693R family,
have the 4 MSB command bits followed by 4 don't care bits.
