[Intel-gfx] [PATCH 19/22] drm/i915: Don't leak framebuffer_references if drm_framebuffer_init() fails

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Don't increment obj->framebuffer_references until we know we actually
managed to create the framebuffer.
