drm/amdgpu: Replace rcu_assign_pointer() with RCU_INIT_POINTER()
The rcu_assign_pointer() ensures that the initialization of a structure is carried out before storing a pointer to that structre. It is always safe to use RCU_INIT_POINTER() to NULL a pointer, instead of rcu_assign_pointer(). This results in slightly smaller/faster code. The following semantic patch was used: <smpl> @@ @@ - rcu_assign_pointer + RCU_INIT_POINTER (..., NULL) </smpl> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Muhammad Falak R Wani <falakreyaz@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
