From: Markus Elfring Date: Mon, 16 Nov 2015 15:40:58 +0100 The ttm_tt_destroy() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring --- dr

[PATCH 1/2] drm: Improve drm_of_component_probe() to correctly handle ports and remote ports.
