2b4e1f6324 staging: comedi: add comedi_inc_scan_progress()
The "comedi_fc" module contains a few functions useful to Comedi
drivers.  Their functionality is being migrated to the core "comedi"
module and renamed to start with the prefix `comedi_`.  As part of this
migration, move `cfc_inc_scan_progress()` into the core comedi module
and rename it to `comedi_inc_scan_progress()`.  Change the external
declaration of `cfc_inc_scan_progress()` into an inline function that
calls `comedi_inc_scan_progress()`.

55deb39b12 staging: comedi: comedi_fc: use comedi_bytes_per_scan()
Since `cfc_bytes_per_scan()` is just an inline function that calls
`comedi_bytes_per_scan()`, replace calls to the former to the latter in
the "comedi_fc" module.  This is part of the migration of functionality
from the "comedi_fc" module to the core "comedi" module.

062fdcada9 staging: comedi: addi_apci_3120: simplify setting of devpriv->us_UseDma
`apci3120_auto_attach()` first sets `devpriv->us_UseDma` to 1, then sets
it back to 0 if it fails to allocate the DMA buffer.  Since `*devpriv`
is initially zeroed out by `comedi_alloc_devpriv()`, change it to only
set `devpriv->us_UseDma` to 1 if the allocation succeeds.  Also, don't
bother explicitly initializing `devpriv->b_DmaDoubleBuffer` to 0 as it
is already zeroed out.

fbfd9c8a17 staging: comedi: addi_apci_3120: use dma_alloc_coherent()
Use `dma_alloc_coherent()` to allocate the DMA buffers instead of
using `__get_free_pages()` to allocate and `virt_to_bus()` to get the
hardware address.  The coherent buffers are fairly small - at most 4
pages (although there are two of them).  Use of `virt_to_bus()` is
discouraged.

Note: `struct addi_private` is used by some other ADDI-DATA drivers as
well, but this is the only one using the affected members.

9c97e588d8 staging: comedi: addi_apci_3120: don't overallocate DMA buffer
The last parameter of `__get_free_pages()` is log2 (the 'order') of the
number of pages to be allocated.  This driver seems to think it is the
linear number of pages, so `apci3120_auto_attach()` first tries to allocate
16 pages, but only uses 4 of them, setting the buffer size to PAGE_SIZE
multiplied by the 'order'.  If the allocation fails, it tries
progressively smaller orders, down to 0.  If the allocation at order 0
succeeds, the buffer size is set to 0, which is likely to cause
problems.

Set the buffer size to `PAGE_SIZE` shifted left by the allocation order.
Since the maximum buffer size previously used was 4, start with an
allocation order of 2 instead of 4.  Rename the `ui_DmaBufferPages` member of
`struct addi_private` to `ui_DmaBufferPageOrder` and rename the `pages`
local variable to `order` to make it clearer what it is.

Note: `struct addi_private` is used by some other ADDI-DATA drivers as
well, but this is the only one using the affected members.

df567feb00 staging: comedi: addi_apci_3120: don't allocate 2nd DMA buffer on failure
`apci3120_auto_attach()` tries to allocate two DMA buffers but may
allocate a single buffer or none at all.  If it fails to allocate the
first buffer, it still tries to allocate the second buffer, even though
it won't be used.  Change it to not bother trying to allocate the second
buffer if the first one fails.

   the naming).  A lot of driver reworking lead up to this - described below.
 
 New features
 * kxcjk1013 - add threshold event support.
 * rockchip - document DT bindings.
 * isl29018 - ACPI support
 * bma180 - enable use without IRQ
 
 Cleanups
 * Tree wide - drop owner field assignment if using the module_platform_driver
   helper as that assigns it anyway.
 * kxcjk1013 - drop a redundant assignment of the current range and fix a
   a defined but not used warning.
 * inv_mpu6050 - Remove an unnecessary cast form a void pointer.
 * rockchip - drop and unused variable.
 * at91_adc - make a local function static.
 * st-sensors-core - correctly handle an error in setting in
   st_sensors_set_drdy_int_pin
 * isl29018 - typo fix
 * bmc150 - fix incorrect scale value for 16G range (Driver new this cycle)
 * bmc150 - fix issues when CONFIG_PM_RUNTIME not set (Driver new this cycle)
 * ad7606 - line length tidy up.
 * bmg160 - set power state only if PM_RUNTIME is defined.
 * ak8975 - fix some unnecessary casting between char * and const char *
 * bma180 - prefix remaining bits and bobs with bma180_ and ensure consistent.
          - use a bool instead of an int for state (as its either on or off).
          - expose the temperature channel
          - statically allocate buffers to avoid need for update_scan_mode
            callback.
          - refactor to allow futher chip variants including support for part
            specific config and disable code + different resolutions.

Pull vfs fixes from Al Viro:
 "double iput() on failure exit in lustre, racy removal of spliced
  dentries from ->s_anon in __d_materialise_dentry() plus a bunch of
  assorted RCU pathwalk fixes"

The RCU pathwalk fixes end up fixing a couple of cases where we
incorrectly dropped out of RCU walking, due to incorrect initialization
and testing of the sequence locks in some corner cases.  Since dropping
out of RCU walk mode forces the slow locked accesses, those corner cases
slowed down quite dramatically.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
