Change (mostly mechanically) every cdevsw/bdevsw I can find to use
...
designated initializers.
I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

ff7e081f9e
Add driver for Nuvoton W83795G voltage/temp/fan/gpio monitoring device.
...
As used in the HP Microserver N36L/N40L/N54L:
w83795g* at iic? addr 0x2f
gpio* at gpiobus?
Note that the gpio and watchdog functionality appears to be useless on
the Microserver, as the gpio pins don't affect the LED's and a watchdog
trigger does not cause a reset. Perhaps the reset pin just isn't wired.
There are quite flexible fan control options as well as just monitoring,
but it is not clear to me how best to export that function to userspace.
