staging: comedi: comedi_fc.h: begin migration to comedidev.h
"comedi_fc.h" contains a few inline functions used by the `do_cmdtest`
handler functions for comedi subdevices in several low-level comedi
drivers for checking asynchronous command trigger sources and arguments.
They all use the prefix `cfc_check_trigger_arg`. Copy them over to
"../comedidev.h", but change the `cfc_` prefix to `comedi_`. Change the
original functions in "comedi_fc.h" into simple wrappers for their
replacements.
Once the drivers have been changed to call the replacement functions,
"comedi_fc.h" can be removed.

staging: comedi: comedi_fops: extend spin-lock scope in comedi_event()
`comedi_event()` is called from low-level drivers to handle comedi
asynchronous command event flags. As a safety check, it checks the
subdevice's "run" flags to make sure an asynchronous command is running.
It can also change the run flags to mark the command as no longer
running (possibly also marking it as terminated with an error).
Checking the runflags and modifying them involves two uses of the
subdevice's spin-lock. It seems better to do it with a single use of
the spin-lock. This also avoids possible interactions with
`do_become_nonbusy()`.
Acquire the subdevice's spin-lock at the start of `comedi_event()` and
release it near the end, before a possible call to `kill_fasync()` (but
after it's parameter values have been determined).
Add and make use of few new inline helper functions:
* `__comedi_clear_subdevice_runflags()` -- clears some run flags without
using the spin-lock
* `__comedi_set_subdevice_runflags()` -- sets some run flags without
using the spin-lock
* `__comedi_get_subdevice_runflags()` -- a spin-lockless version of
`comedi_get_subdevice_runflags()
* `__comedi_is_subdevice_running()` -- a spin-lockless version of
* `comedi_is_subdevice_running()`

`comedi_event()` is called from low-level drivers to handle comedi
asynchronous command event flags. Some events cause waiting tasks to be
woken up, and a `SIGIO` signal to be sent via `kill_fasync()`. The
signal code is `POLL_OUT` if the subdevice supports commands in the
"write" direction, or `POLL_IN` for the "read" direction. If the
subdevice supports commands in either direction, it sends two `SIGIO`
signals, one with each code. Change that latter case to only send one
`SIGIO` signal, using the direction of the current command to determine
the signal code. If the `CMDF_WRITE` flag is set in the current
command, it's in the "write" direction, otherwise it's in the "read"
direction.

`comedi_is_subdevice_in_error()` is only used by `comedi_read()` and

`comedi_is_subdevice_running()` returns `false` (with extra conditions
in the case of `comedi_write()`). `comedi_is_subdevice_running()` and

`comedi_get_subdevice_runflags()` which uses the subdevice's spin-lock.
Eliminate one use of the subdevice's spin-lock in `comedi_read()` and
`comedi_write()` by calling `comedi_get_subdevice_runflags()` and
checking the runflags directly. Add a couple of inline functions to
check the runflags: `comedi_is_runflags_running()` and
`comedi_is_runflags_in_error()`. These do the same test on runflags as

get passed the runflags value directly.
`comedi_is_subdevice_in_error()` is no longer used, so remove it.

`comedi_set_subdevice_runflags()` changes the comedi subdevice's
`runflags` member according to a bit-mask and new bit values. It's name
might suggest that it only "sets", not "clears". Rename it to
`comedi_update_subdevice_runflags()` to avoid confusion.

Merge lustre patches based on 4.0-rc5 into staging-testing
This is done to handle some lustre patches that were made against the
wrong kernel branch, which was my fault, as I gave a lecture where I
messed things up for the students, it wasn't their fault.

staging: lustre: include: replace OBD_CHECK_DEV_ACTIVE by obd_check_dev_active
Static inline functions are preferred over macros. The inline function
obd_check_dev_active is introduced to replace OBD_CHECK_DEV_ACTIVE.
All functions that call obd_check_dev_active store the return values
and return them if they represent an error code.
Some of the changes were carried out manually while others were done
using coccinelle.

Power down device when an error occurs in order to avoid wasting
power. Move powerdown function up to be seen by the new call and
align parameters for the ltr501_write_contr() call.

staging: dgnc_sysfs: Replace printk(KERN_ERR ) with pr_err()
Fix the following checkpatch warning:
WARNING: Prefer [subsystem eg: netdev]_err([subsystem]dev, ...
then dev_err(dev, ... then pr_err(... to printk(KERN_ERR ...
Staging: lustre: Mark internal functions static in llog_cat.c
This patch marks functions llog_cat_set_first_idx and cat_cancel_cb
static as these are used only within this file. Also since cat_cancel_cb
is made static do not export it.
This eliminates the following sparse warning:
warning: symbol * was not declared. Should it be static?
Staging: lustre: Include header for functions prototypes
This patch includes the header lustre/include/lclient.h that declares
the functions lov_lsm_put and lov_read_and_clear_async_rc defined in
lov_object.c.
This eliminates warnings reported by sparse:
warning: symbol was not declared. Should it be static?
Staging: lustre: Add function prototypes in console.h
Sparse reported the following warnings:
warning: symbol 'lstcon_console_init' was not declared. Should it be static?
warning: symbol 'lstcon_console_fini' was not declared. Should it be static?
warning: symbol 'lstcon_ioctl_entry' was not declared. Should it be static?
However since these functions are used in other files,
they cannot be made static, so add protoypes for the same in console.h.
