iio: Simplify iio_map_array_unregister API

Instead of requiring the map to unregister, simply unregister all map entries
associated with the given iio device. This simplifies map removal and also works
for maps generated through devicetree.

iio/adc: (max1363) Fix data conversion problems

For chips with more than 8 bit ADC resolution, received data was always
masked against 0xfff, ie with a 12 bit mask. This can result in bad data
for chips with 10 bit resolution if those chips have higher bits set
(seen with MAX1139).

The receive buffer was defined as char array. This could result in
unintentional sign extensions if the upper bit in a received byte
was set. Since the chip is configured for unipolar mode, we never
have to handle negative values, and sign extensions are never needed.

staging: comedi: cleanup all board minors on module exit

The comedi core module optionally allocates some legacy board minor
devices on module load and cleans these up on module exit.  These are
used for manual configuration of comedi boards (for those low-level
comedi drivers that support manual configuration - mainly for ISA
boards).  Other board minor devices are created and destroyed
dynamically in response to bus device probe and remove requests.  The
ioctl used for manual configuration (attachment) and removal
(detachment) of devices is COMEDI_DEVCONFIG, but that works for any
board minor device, including those that were originally created
dynamically.

If the COMEDI_DEVCONFIG ioctl is used to manually detach an
automatically created and attached device, commit
7d3135af399e92cf4c9bbc5f86b6c140aab3b88c ("staging: comedi: prevent
auto-unconfig of manually configured devices") ensures that the board
minor will no longer be automatically detached and destroyed by a bus
device remove request.  From that point on the board minor behaves more
like one of the comedi "legacy" board minors.  (There would be some
justification for destroying the board minor instead, but I'd rather
leave that decision until removal of board minors has been
made safer than it currently is.)  Although the board minor behaves more
like a legacy board minor, it is not currently cleaned up on module
exit.  In fact, the module exit code will bug out because this board
minor has not been cleaned up.

Change comedi_cleanup_legacy_minors() (called from the module exit code,
and from the module init code on error) to clean up all board minors.
Rename the function to comedi_cleanup_board_minors() to reflect the
change in functionality.

staging: comedi: disallow COMEDI_DEVCONFIG on non-board minors

Comedi has two sorts of minor devices:
(a) normal board minor devices in the range 0 to
COMEDI_NUM_BOARD_MINORS-1 inclusive; and
(b) special subdevice minor devices in the range COMEDI_NUM_BOARD_MINORS
upwards that are used to open the same underlying comedi device as the
normal board minor devices, but with non-default read and write
subdevices for asynchronous commands.

The special subdevice minor devices get created when a board supporting
asynchronous commands is attached to a normal board minor device, and
destroyed when the board is detached from the normal board minor device.
One way to attach or detach a board is by using the COMEDI_DEVCONFIG
ioctl.  This should only be used on normal board minors as the special
subdevice minors are too ephemeral.  In particular, the change
introduced in commit 7d3135af399e92cf4c9bbc5f86b6c140aab3b88c ("staging:
comedi: prevent auto-unconfig of manually configured devices") breaks
horribly for special subdevice minor devices.

Since there's no legitimate use for the COMEDI_DEVCONFIG ioctl on a
special subdevice minor device node, disallow it and return -ENOTTY.

make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
make: *** Waiting for unfinished jobs....

The reason we used that function is copy method by [1]
was really slow in ARM but at that time.

More severe problem is ARM can prefetch speculatively on other CPUs
so under us, other TLBs can have an entry only if we do flush local
CPU. Russell King pointed that. Thanks!
We don't have many choices except using flush_tlb_kernel_range.

My experiment in ARMv7 processor 4 core didn't make any difference with
zsmapbench[2] between local_flush_tlb_kernel_range and flush_tlb_kernel_range
but still page-table based is much better than copy-based.

* bigger is better.

1. local_flush_tlb_kernel_range: 3918795 mappings
2. flush_tlb_kernel_range : 3989538 mappings
3. copy-based: 635158 mappings

This patch replace local_flush_tlb_kernel_range with
flush_tlb_kernel_range which are avaialbe in all architectures
because we already have used it in vmalloc allocator which are
generic one so build problem should go away and performane loss
shoud be void.

staging: comedi: simplify comedi_set_hw_dev()

Since `get_device()` and `put_device()` can take a NULL device
parameter, `comedi_set_hw_dev()` can be simplified to always call
`get_device()` for the new, possibly NULL hardware device, and
`put_device()` for the old, possibly NULL hardware device.  As long as
we do it in that order, there shouldn't be any problem with
`kref_release()` getting called unexpectedly when the new hardware
device is the old hardware device.

function is used for additional purposes since the old comment was
written.

staging: comedi: don't override read/write subdevice if not supported

For comedi devices that support asynchronous commands on some of their
subdevices, the comedi core creates extra device files for each of those
subdevices of the form "/dev/comedi%i_subd%i".  These use the same
comedi device as the corresponding "/dev/comedi%i" but override the
default "read" and "write" subdevice for the device.  Currently it
overrides both the read and write subdevice, but it only makes sense to
override the "read" subdevice if the subdevice supports "read" commands,
and to override the "write" subdevice if the subdevice supports "write"
commands.

In `comedi_alloc_subdevice_minor()`, only set `info->read_subdevice`
non-NULL if the subdevice has the `SDF_CMD_READ` flag set, and only set
`info->write_subdevice` non-NULL if the subdevice has the
`SDF_CMD_WRITE` flag set.  (`comedi_read_subdevice(info)` will use the
device's default read subdevice if `info->read_subdevice` is NULL.
`comedi_write_subdevice(info)` will use the device's default write
subdevice if `info->write_subdevice` is NULL.
