[PATCH 3/7] drm: Replace drm_gem_object_{un/reference} with drm_gem_object_{put, get}

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch unifies the naming of DRM functions for reference counting
of struct drm_gem_object. The resulting code is more aligned with the
rest of the Linux kernel interfaces.

The patch also deletes the old functions and removes them from the
Coccinelle script.
