The 'thisboard' macro relies on a local variable having a specific

Replace the macro with a local variable and use the comedi_board()

Absorb the code from dio24_config() into the probe function,
dio24_cs_attach() and properly return the error code when the
probe fails. This also gets rid of an unnecessary forward

For aesthetic reasons, move the remove functio, dio24_cs_detach(),
so it's after the probe function.

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
7d3135af39 ("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.

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 7d3135af39 ("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.

When a port has been reserved in an attempt to connect to a peer
but that attempt does not succeed, releasing the port should not
reset the port line status. Although resetting is functionally
harmless, it can appear as if a remote peer dropped carrier to a
port it was not attached to (which can be confusing).
