    Exactly. We essentially have a flat namespace for modules, despite
    the fact of them being organized into directories. At least for the
    subsystems I maintain, I'd like to have a consistent prefix for that

    On a brief survey of drivers:

    apci: *.c
    ata: pata_*.c, sata_*.c
    atm: *.c
    block: *.c
    bluetooth: *.c
    crypto: *.c
    dma: *dma.c
    gpio: gpio-*.c (after applying my patch)
    hid: hid-*.c
    hwmon: *.c
    i2c: i2c-*.c
    ide: *.c and ide-*.c
    input: *.c
    leds: leds-*.c
    mca: mca-*.c
    md: largely dm-*.c
    mfd: *.c
    mmc: *.c
    mtd: *.c
    net: *.c
    rtc: rtc-*.c
    scsi: *.c and scsi_*.c for core code
    spi: (before patch) mix of spi_*.c and *_spi.c and *.c
    uio: uio_*.c
    virtio: virtio_*.c
    wdt: *wdt.c and *_wdt.c

    So, in this (admittedly incomplete) survey, I see 5 users of the
    "prefix_" pattern, 8 of the "prefix-" pattern, a small number using a
    suffix, and a whole lot without any pattern at all. Personally, I
    prefer the using a prefix with a '-', but in the spi directory there
    was already a number of drivers using '_', so it was smaller impact to
    change to using that instead of a dash. If people don't think it is a
    big deal though, then I'll change it to '-' to match the gpio change.
