int drm_get_minor	(	struct drm_device *	dev,
		struct drm_minor **	minor,
		int	type
	)

Get a secondary minor number.

Parameters

dev	device data structure
sec-minor	structure to hold the assigned minor

Returns

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().

Definition at line 446 of file drm_stub.c.

int drm_put_minor

(

struct drm_minor **

minor_p

)

Put a secondary minor number.

Parameters

sec_minor

- structure to be released

Returns

always zero

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