Lets make a habit not to put editor-related magic into our base
files.  They are redundant and useless.

   33: .Sh NAME
   34: .Nm BUS_READ_IVAR ,
   35: .Nm BUS_WRITE_IVAR
   36: .Nd manipulate bus-specific device instance variables
   37: .Sh SYNOPSIS
   38: .In sys/param.h
   39: .In sys/bus.h
   40: .Ft int
   41: .Fn BUS_READ_IVAR "device_t dev" "device_t child" "int index" "uintptr_t *result"
   42: .Ft int
   43: .Fn BUS_WRITE_IVAR "device_t dev" "device_t child" "int index" "uintptr_t value"
   44: .Sh DESCRIPTION
   45: These two methods manage a bus specific set of instance variables of
   46: a child device.  The intention is that each different type of bus
   47: defines a set of appropriate instance variables (such as ports and
   48: irqs for ISA bus etc.)
   49: .Pp
   50: This information could be given to the child device as a struct but
   51: that makes it hard for a bus to add or remove variables without
   52: forcing an edit and recompile for all drivers which may not be
   53: possible for vendor supplied binary drivers.
   54: .Sh RETURN VALUES
   55: Zero is returned on success, otherwise an appropriate error is returned.
   56: .Sh SEE ALSO
   57: .Xr device 9 ,
   58: .Xr driver 9
