NAME¶
drm_dev_ref - Take reference of a DRM deviceSYNOPSIS¶
void
drm_dev_ref(struct drm_device * dev);
ARGUMENTS¶
devdevice to take reference of or NULL
DESCRIPTION¶
This increases the ref-count of dev by one. You *must* already own a reference when calling this. Use drm_dev_unref to drop this reference again. This function never fails. However, this function does not provide *any* guarantee whether the device is alive or running. It only provides a reference to the object and the memory associated with it.AUTHORS¶
