    Message : Increase the default count of /dev/videoX from 2 to 4 It's quite common for a laptop to have a visible light camera, an infrared camera, or both, in addition to a camera connected via USB. OK: sthen@ ratchov@ mglocker@ armani@

    dnl Common device definitions.
    dnl
    dnl This file contains the MI device definitions (as well as some MD
    dnl definitions not cleaned up yet...)
    dnl
    dnl Diversions:  (upon termination, concatenated output queues)
    dnl
    dnl 0 - very top
    dnl 1 - descriptions of devices
    dnl 2 - init of script, function definitions, etc
    dnl 3 - beginning of global recursive R() function
    dnl 7 - body of MAKEDEV, device creations, etc
    dnl 9 - end
    dnl
    dnl Diversions 2, 3 and 7 are not filled when generating the manual page.
    dnl
    dnl HOW TO ADD A DEVICE:
    dnl
    dnl In this file, you must use at least two macros:
    dnl
    dnl  Use '__devitem(uniqueid, name-pattern, description)' to create an entry
    dnl  in the description at the top of the generated MAKEDEV file:
    dnl
    dnl    __devitem(sca, sca*, Sugar Generic device)dnl
    dnl    __devitem(cry, crypto, hardware crypto access driver)dnl
    dnl
    dnl  This is ultimately shown as:
    dnl
    dnl    #  sca*   Sugar Generic device
    dnl    #  crypto hardware crypto access driver
    dnl
    dnl  Use '_mkdev(uniqueid, shell-pattern, {-shell-script-})dnl' to create
    dnl  a shell script fragment used to 'create' the device (be sure to match
    dnl  the uniqueid from above):
    dnl
    dnl    _mkdev(sca, sca*, {-M sca$U c major_sca_c $U
    dnl           M rsca$U b major_sca_b Add($U, 128)-})dnl
    dnl    _mkdev(cry, crypto, {-M crypto c major_cry_c 0-})dnl
    dnl
    dnl  This is ultimately expanded into:
    dnl
    dnl    sca*)
    dnl           M sca$U c 24 $U
    dnl           M sca$U b 42 $(($U+128))
    dnl           ;;
    dnl
    dnl    crypto)
    dnl           M crypto c 47 0
    dnl           ;;
    dnl
    dnl In the MAKEDEV.md file, add a '_DEV(uniqueid, charmajor, blockmajor)'
    dnl entry:
    dnl
    dnl   _DEV(sca, 24, 42)
    dnl   _DEV(cry, 47)
    dnl
    dnl Final step is to use the 'target/twrget' macros to have the 'all)' target
    dnl generate one or more device(s).  Usage of 'target/twrget' is:
    dnl      target(target_name, device_name [, append_string ] .. )
    dnl      twrget(target_name, uniqueid, device_name, [, append_string ] .. )
    dnl
    dnl        target_name   a unique name that later is used as an argument to
    dnl                      'show_target()' (which expands all devices for a
    dnl                      given 'target_name').
    dnl        uniqueid      same as 'uniqueid' above
    dnl        device_name   string representing the device to be mknod'ed
    dnl        append_string for each append_string, `device_name' is prepended
    dnl
    dnl Note: 'target(a,b,c)' is equivalent to 'twrget(a,b,b,c)'
    dnl
    dnl
    dnl For a short example:
    dnl
    dnl   target(all, std)dnl
    dnl   target(all, sca, 0, 1, 2, 3)dnl
    dnl   twrget(all, cry, crypto)dnl
    dnl
    dnl would expand to:
    dnl
    dnl   all)
    dnl        R std sca0 sca1 sca2 sca3 crypto
    dnl        ;;
    dnl
    dnl presuming '_DEV(sca, ?, ?)' and '_DEV(std)' were in the MAKEDEV.md file.
    dnl
    dnl
    dnl Everything is 'automatically' added to 'MAKEDEV' based on whether or
    dnl not the '_DEV()' entry has a corresponding _mkdev() and __devitem()
    dnl entry in MAKEDEV.mi (this file).
    dnl
    dnl Note: be very wary of adding whitespace, carriage returns, or not
    dnl finishing a macro with ')dnl' .. otherwise, extra blank lines show up
    dnl in the output.
    dnl
    dnl TODO:
    dnl
    dnl make a 'disktgt' macro that automatically does:
    dnl disktgt(rd, {-rd-})
    dnl
    dnl	target(all,rd,0)
    dnl	target(ramd,rd,0)
    dnl	disk_q(rd)
    dnl	__devitem(rd, {-rd*-}, {-rd-})dnl
    dnl
    dnl  Note: not all devices are generated in 'all)' below. MAKEDEV.md contains
    dnl        its own extra list.
