      staging: lustre: rename cfs_cpt_table to cfs_cpt_tab · 457d63ea
      NeilBrown authored 
      The variable "cfs_cpt_table" has the same name as
the structure "struct cfs_cpt_table".
This makes it hard to use #define to make one disappear
on a uni-processor build, but keep the other.
So rename the variable to cfs_cpt_tab.

      staging: lustre: move files out of lustre/lnet/libcfs/linux/ · f72c3ab7
      NeilBrown authored 
      There is no longer any value in having this separate
subdirectory, so promote the files in it.
Also tidy the Makefile a little to use the common "*-obj-y"
macro name.  This will allow individual files to be conditionally
compiled.

      staging: lustre: refactor libcfs initialization. · 64bf0b1a
      NeilBrown authored 
      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.

      staging: lustre: osc: tidy up osc_init() · e67f133d
      NeilBrown authored 
      A module_init() function that registers the services
of the module should do that last, after all other
initialization has succeeded.
This patch moves the class_register_type() call to the
end and ensures everything else that might have been
set up, is cleaned up on error.

      Merge tag 'iio-for-4.18b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

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.
