This patch set replaces the occurrences of drm_*_reference() and drm_*_unreference() with the new drm_*_get() and drm_*_put() functions. All patches in the series do the same thing, converting to the new APIs. I created patches per DRM driver as suggested by Daniel Vetter. Background: In the kernel, reference counting APIs use *_get(), *_put() style naming to reference-count the objects. But DRM

drm_*_reference() and drm_*_unreference() functions are just compatibility alias for drm_*_get() and drm_*_put() adn should not be used by new code. So convert all users of compatibility functions to use the new APIs.

This is a false positive, but I wonder if it is really necessary to put the assignment in the conditional test expression. julia ---------- Forwarded message ---------- Date: Tue, 28 Nov 2017 13:23:36 +0800 From: kbuild test robot <fengguang.wu at intel.com> To: kbuild at 01.org Cc: Julia Lawall <julia.lawall at lip6.fr> Subject: [PATCH] drm/nouveau/mmu: fix odd_ptr_err.cocci

Hi julia, I think it would be better to extract the assignment out of the if clause. Then you'll get something like this: memory = ...; if (IS_ERR(memory)) { .... } so, to answer your question: no, it isn't necessary.

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.
