From fe094dad25ec28585a591db823c768af2b2be1f4 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 19 Jul 2016 14:54:16 -0300 Subject: [PATCH] [media] v4l2-common: Delete an unnecessary check before the function call "spi_unregister_device" The spi_unregister_device() 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.
