| H A D | msm_gem.c | 2203bd0e Wed Oct 13 03:13:15 CDT 2021 Dan Carpenter <dan.carpenter@oracle.com> drm/msm: uninitialized variable in msm_gem_import()
The msm_gem_new_impl() function cleans up after itself so there is no
need to call drm_gem_object_put(). Conceptually, it does not make sense
to call a kref_put() function until after the reference counting has
been initialized which happens immediately after this call in the
drm_gem_(private_)object_init() functions.
In the msm_gem_import() function the "obj" pointer is uninitialized, so
it will lead to a crash.
