Fixup the MODULE_DESCRIPTION for several lustre modules. Some wrongly
place the version in the string or they are not descriptive enough.

c732623b0b staging: unisys: visorbus: tolerate larger-than-expected controlvm channel
Use the dynamic size of the controlvm channel (struct channel_header.size)
instead of the statically computed sizeof(struct controlvm_channel) when
determining the valid bounds for visorchannel_read() and
visorchannel_write().

This prevents an observed problem where kdump was failing because
controlvm_channel.local_crash_msg_offset was pointing beyond the statically
computed size of the channel, even though the channel was physically large
enough.  This was causing visorchannel_read() to unecessarily fail, because
we thought we were attempting to access memory outside of the channel.

a8deaef370 staging: unisys: visorbus: fix payload memory usage in controlvm channel
Previously if controlvm message payloads (indicated in controlvm message
via struct controlvm_message.hdr.payload_vm_offset) were contained within
the bounds of the channel memory, we would fail to process any controlvm
message that contained payload data.  Reason is, the request_mem_region()
would fail, because it overlapped the channel memory.  Since
request_mem_region() doesn't actually serve a functional purpose anyway,
this was simply removed.

ec3c13e4ac Third set of IIO new device support, features and cleanups for the 4.6 cycle.
Good to see several new contributors in this set - and more generally a
 number of new 'faces' over this whole cycle.
 
 Staging movements
 * hmc5843
   - out of staging.
 * periodic RTC trigger
   - driver dropped.  This is an ancient driver (brings back some memories ;)
   that was always somewhat of a bodge. Originally there was a driver that
   never went into mainline that supported large numbers of periodict timers
   on the PXA270 via this route. Discussions to have a generic periodic
   timer subsystem never went anywhere.  At the time RTC periodic
   interrupts were real - now they are emulated using high resolution
   timers so with the HRT driver this has become pointless.
 
 New device support
 * mpu6050 driver
   - Add support for the mpu6500.
 * TI tpl0102 potentiometer
   - new driver.
 * Vybrid SoC DAC
   - new driver.  The ADC on this SoC has been supported for a while, this
     adds a separate driver for the DAC.
 
 New Features
 * hmc5844
   - Attributes to configure the bias current (typically part of a self test)
     This could be done before via a somewhat obscure custom interface.
     This at least makes it easy to tell what is going on.
   - Document all custom attributes.
 * mpu6050
   - Add support for calibration offset control and readback.
 * ms5611
   - power regulator support.  This is always one that gets added the
     first time someone has a board that needs it.  Here it was needed,
     hence it was added.
 
 Cleanups / minor fixes
 * tree wide
   - clean up all the myriad different return values in response to a
     failure of i2c_check_functionality.  After discussions everyone seemed
     happy wiht -EOPNOTSUPP which seems to describe the situation well.
     I encouraged a tree wide cleanup to set a good example in future for
     this.
 * core
   - Typos in the iio_event_spec documentation in iio.h
 * afe4403
   - select REGMAP_SPI to avoid dependency issues
   - mark suspend/resume as __maybe_unused to avoid warnings
 * afe4404
   - mark suspend/resume as __maybe_unused to avoid warnings
 * atlas-ph-sensor
   - switch the regmap cache type from linear to rbtree to gain reading of
     registers on initial startup.  It's not immediately obvious, but
     regmap flat is meant for high performances cases so doesn't read these
     registers.
   - use regmap_bulk_read in one case where it was using
     i2c_smbus_read_i2c_block_data directly (unlike everything else that was
     through regmap).
 * ina2xx
   - stype cleanups (lots of them!)
 * isl29018
   - Get the struct device back from regmap rather than storing another
     copy of it in the private data.  This cleanup makes sense in a number
     of other drivers so patches may well follow.
 * mpu6050
   - style cleanups (lots of them!)
   - improved return value handling
   - use usleep_range to avoid the usual issues with very short msleeps.
   - add some missing documentation.
 * ms5611
   - use the probed device name for the device rather than the driver name.
   - select IIO_BUFFER to avoid dependency issues
 * palmas
   - drop IRQF_EARLY_RESUME as no longer needed after genirq changes.

Jonathan writes:

Third set of IIO new device support, features and cleanups for the 4.6 cycle.

Good to see several new contributors in this set - and more generally a
number of new 'faces' over this whole cycle.

Staging movements
* hmc5843
  - out of staging.
* periodic RTC trigger
  - driver dropped.  This is an ancient driver (brings back some memories ;)
  that was always somewhat of a bodge. Originally there was a driver that
  never went into mainline that supported large numbers of periodict timers
  on the PXA270 via this route. Discussions to have a generic periodic
  timer subsystem never went anywhere.  At the time RTC periodic
  interrupts were real - now they are emulated using high resolution
  timers so with the HRT driver this has become pointless.

New device support
* mpu6050 driver
  - Add support for the mpu6500.
* TI tpl0102 potentiometer
  - new driver.
* Vybrid SoC DAC
  - new driver.  The ADC on this SoC has been supported for a while, this
    adds a separate driver for the DAC.

New Features
* hmc5844
  - Attributes to configure the bias current (typically part of a self test)
    This could be done before via a somewhat obscure custom interface.
    This at least makes it easy to tell what is going on.
  - Document all custom attributes.

    first time someone has a board that needs it.  Here it was needed,
    hence it was added.
