gcc-7 detects that wlanhdr_to_ethhdr() in two drivers calls memcpy() with
a destination argument that an earlier function call may have set to NULL:
staging/rtl8188eu/core/rtw_recv.c: In function 'wlanhdr_to_ethhdr':
staging/rtl8188eu/core/rtw_recv.c:1318:2: warning: argument 1 null where non-null expected [-Wnonnull]
staging/rtl8712/rtl871x_recv.c: In function 'r8712_wlanhdr_to_ethhdr':
staging/rtl8712/rtl871x_recv.c:649:2: warning: argument 1 null where non-null expected [-Wnonnull]
I'm fixing this by adding a NULL pointer check and returning failure
from the function, which is hopefully already handled properly.
This seems to date back to when the drivers were originally added,
so backporting the fix to stable seems appropriate. There are other
related realtek drivers in the kernel, but none of them contain a
function with a similar name or produce this warning.

The driver's COMEDI "auto-attach" handler `db2k_auto_attach()` calls
`db2k_find_boardinfo()` to find an element of our board information
array `db2k_boardtypes[]` that matches the probed PCI device. The
driver's PCI device table matches several boards in the DaqBoard/2000
series that match a single PCI vendor and device ID combination.
`db2k_find_boardinfo()` uses the probed PCI device's subvendor and
subdevice IDs to find the matching board information, returning `NULL`
for no match.
Change the driver's PCI device table `db2k_pci_table[]` to match
supported PCI vendor, device, subvendor and subdevice IDs, and set the
`.driver_data` member of each element to the index of the matching
element of `db2k_boardtypes[]`. That index gets passed through to the
COMEDI auto-attach handler `db2k_auto_attach()`. Use it to index
directly into `db2k_boardtypes[]` instead of calling
`db2k_find_boardinfo()` to find the match.
Use array index designators in the initializer of `db2k_boardtypes[]`.
Use enumerated constants defined by new type `enum db2k_boardids` to
name the board type indices.
The `id` member of `struct db2k_boardtype` is no longer used, so remove
it. Also remove the subdevice ID macros `DB2K_SUBSYSTEM_IDS2` and
`DB2K_SUBSYSTEM_IDS4` as the subdevice IDs are now specified as numbers
in the PCI device table. Remove `db2k_find_boardinfo()` as it is no
longer used.

The driver supports DaqBoard/2000 and DaqBoard/2001. DaqBoard/2000 has 2
AO channels, but DaqBoard/2001 has 4 AO channels. The driver currently
only supports 2 AO channels, but supporting 4 channels is just a case of
setting the `n_chan` member of the COMEDI subdevice to 4 instead of 2.
Add a new boolean flag member `has_2_ao` to `struct db2k_boardtype` to
be set to `true` if the board only has 2 AO channels. Set this to
`true` in the element of `db2k_boardtypes[]` that corresponds to the
DaqBoard/2000. Use it in `db2k_auto_attach()` to initialize the number
of AO channels to 2 or 4, as appropriate.

According to an old GPL'ed driver at
<ftp://ftp.mccdaq.com/downloads/iotech_software/DaqBoard_1000_2000_Series/Linux_driver_kernelv2.4.x/>,
The CPLD status register can be checked to make sure that it is ready to
accept the next 16-bit word of FPGA firmware data, but that doesn't work
on older versions of the CPLD, where a simple delay should be used
between successive writes. The current version of the Comedi driver
just uses a delay between successive writes. Change it to check for the
newer CPLD in the `daqboard2000_load_firmware()`, and change the
firmware word writing function `daqboard2000_write_cpld()` to wait for
the status bit (`DB2K_CPLD_STATUS_TXREADY`, previously called
`DB2K_CPLD_TXDONE`) to be set for newer CPLD, or just delay for older CPLD.
Return an error if it times out waiting for the status bit.
The wait for the `DB2K_CPLD_STATUS_TXREADY` status bit to be set is
performed by new function `daqboard2000_wait_cpld_txready()`, which
returns 0 if the status bit is set within 100 microseconds, or
`-ETIMEDOUT` if not.
