From 0dc8fe5985e01f238e7dc64ff1733cc0291811e8 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Wed, 2 Oct 2013 11:23:37 +0200 Subject: drm: introduce drm_dev_free() to fix error paths The error paths in DRM bus drivers currently leak memory as they don't correctly revert drm_dev_alloc(). Introduce drm_dev_free() to free DRM devices which haven't been registered, yet. We must be careful not to introduce any side-effects with cleanups done in drm_dev_free(). drm_ht_remove(), drm_ctxbitmap_cleanup() and drm_gem_destroy() are all fine in that regard.
