a55de0f493 staging: comedi: comedi_bond: use krealloc() and fix memory leak
`do_dev_config()` is called from the comedi 'attach' handler,
`bonding_attach()`.  The device private data structure contains a
dynamically allocated array of pointers to "bonded" device structures
which grows during the `do_dev_config()` call.  The length of this array
is in `devpriv->ndevs`.  It currently uses a local function `realloc()`
to allocate a new array, copy the old contents over and free the old
array.  It should be more efficient to use `krealloc()` as it may be
able to use slack space at the end of the previous array and avoid a
copy.

The old `realloc()` function always freed the old buffer which meant
that if it failed to allocate the new buffer it would lose the contents
of the old buffer.  Unfortunately, that contained pointers to more
dynamically allocated memory, leading to a memory leak.  If `krealloc()`
fails, keep the old buffer and avoid the memory leak.  The
aforementioned pointers to more dynamically allocated memory will be
cleaned up by the 'detach' handler, `bonding_detach()` which will be
called by the comedi core as a consequence of `krealloc()` failing in
`do_dev_config()`.

0f3ce1a600 staging: comedi: comedi_bond: handle base channel for insn_bits
If a DIO subdevice has more than 32 channels, its 'insn_bits' handler is
supposed to take account of the base channel from
`CR_CHAN(insn->chanspec)`.  (The comedi core will adjust the base
channel to 0 and shift the mask and data to compensate if the subdevice
has less than or equal to 32 channels.)  The "comedi_bond" driver
currently ignores the base channel and assumes it is 0.

Replace `comedi_dio_bitfield()` in the "kcomedilib" module with
`comedi_dio_bitfield2()` that takes account of the base channel, and
rewrite the "comedi_bond" driver's 'insn_bits' handler
(`bonding_dio_insn_bits()`) to take account of the base channel and use
the new function.

No other modules use `comedi_dio_bitfield()` so it is safe to replace it
with `comedi_dio_bitfield2()`.  The name follows that of the equivalent
function in the user-space comedilib.  If the base channel is non-zero
and the subdevice has less than or equal to 32 channels it needs to
adjust things in the same way as the comedi core (same as `parse_insn()`
in "comedi_fops.c") due to most drivers ignoring the base channel.

16d2d3cbb3 staging: comedi: comedi_bond: get INSN_CONFIG_DIO_QUERY info from horse's mouth
The DIO subdevice of the "comedi_bond" device attempts to remember the
directions of DIO channels itself in the `io_bits` member of the
subdevice, but that is only large enough for the first 32 channels and
it might not be accurate anyway as changing the direction of one channel
may have affected a whole group of channels and we have no idea of the
initial directions before the "bonded" device was linked to the the
"comedi_bond" device.  It would be better to ask the bonded device for
this information when handling a `INSN_CONFIG_DIO_QUERY` configuration
instruction.  Add new function `comedi_dio_get_config()` to the
"kcomedilib" module to allow us to get the DIO direction of a channel
and use it.

10b799d2fe staging: comedi: comedi_bond: don't map channels individually
The private data structure (`struct comedi_bond_private`) for the
overall "comedi_bond" device maps each channel individually to a pointer
to the `struct bonded_device` it belongs to via array member
`chan_id_dev_map[MAX_CHANS]`. This speeds up look-ups from channel
number to bonded device a bit, but the length of the array used to look
this up is currently fixed at `MAX_CHANS` (256) and there are no
overflow checks when filling the array.

In practice, there will only be a few bonded devices (actually bonded
subdevices) and it is practical to just skip through the list until we
reach the one containing the desired channel.

The only place where the bonded device is looked up from the channel
number is in `bonding_dio_insn_config()`.  Change it to do the look-up
by skipping through the list of bonded devices and remove the
`chan_id_dev_map[]` member.  The `chanid_offset` member of `struct
bonded_device` is also no longer needed as the value can be derived
while skipping through the list of bonded devices, so remove that member
as well.

f59ebeda20 staging: comedi: comedi_bond: use bitmap to record opened/closed minors
`do_dev_config()` currently records the comedi minor devices it has
opened by setting `devs_opened[minor]` to the pointer returned by
`comedi_open()`.  This is checked to avoid opening the same minor device
twice.  The pointer values in `devs_opened[]` aren't needed; we only
need to record which minor device numbers are being used.  Change
`devs_opened` to a bitmap (declared with `DECLARE_BITMAP()`) of length
`COMEDI_NUM_BOARD_MINORS` as the minor device numbers are range-checked
to fit in a bitmap of this length.  Use `test_and_set_bit()` to record
the minor device numbers we attempt to open with `comedi_open()`.

`bonding_detach()` calls `comedi_close()` to close the comedi minor
devices.  Since the minor device numbers may be repeated in its list of
bonded subdevices, it currently uses a simple `unsigned long
devs_closed` variable as a bitmap to keep track of which minor device
numbers it has already closed to avoid closing them twice.  As a single
`unsigned long` consists of less than `COMEDI_NUM_BOARD_MINORS` bits on
a 32-bit machine, change `devs_closed to a bitmap of this length using
`DECLARE_BITMAP()` and use `test_and_set_bit()` to avoid calling
`comedi_close()` more than once for each minor device number in use.

`bonding_attach()` is the comedi "attach" handler for the driver.  Any
non-negative return value is treated as successful, but 0 is the
preferred return value on success.

The `char file[]` variable in `do_dev_config()` doesn't need to be
initialized as it gets overwritten with a `snprintf()`.  It just needs
