Return status ENXIO / ESRCH in kern_drvctl.c

[Paul Goyette <paul%whooppee.com@localhost>]

While browsing the code for other stuff, I ran into what appears to be 
an inconsistency in drvctl(4).

In most cases, when the device specified cannot be found, we return 
ENXIO - Device not configured.

But in routine drvctl_command_get_properties(), if the device is not 
found, we return ESRCH - No such process.  (This is in file 
sys/kern/kern_drvctl.c rev 1.32 at line 462)

It seems to me that this is incorrect, and we should return ENXIO here.


As a side note, it would be nice if we had a drvctl(4) man page.   :)
