25 \fBddi_driver_major()\fR returns the major device number for the driver
26 associated with the supplied \fBdev_info node\fR. This value can then be used
27 as an argument to \fBmakedevice\fR(9F) to construct a complete \fBdev_t\fR.
35 A pointer to the device's \fBdev_info\fR structure.
41 \fBddi_driver_major()\fR returns the major number of the driver bound to a
42 device, if any, or \fBDDI_MAJOR_T_NONE\fR otherwise.
46 \fBddi_driver_major()\fR can be called from kernel or interrupt context.
