int drm_get_minor ( struct drm_device dev,

Get a secondary minor number.

devdevice data structure
sec-minorstructure to hold the assigned minor
negative number on failure.

Search an empty entry and initialize it to the given parameters, and create the proc init entry via proc_init(). This routines assigns minor numbers to secondary heads of multi-headed cards

void drm_put_dev ( struct drm_device dev)

Called via drm_exit() at module unload time or when pci device is unplugged.

Cleans up all DRM device, calling drm_lastclose().

int drm_put_minor ( struct drm_minor **  minor_p)

Put a secondary minor number.

sec_minor- structure to be released
always zero

Cleans up the proc resources. Not legal for this to be the last minor released.
