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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
