From 0d51573df3e0d944a644dbe90cdb06afefe77cc4 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 3 Sep 2022 12:41:15 +0200 Subject: [PATCH] media: atomisp: Remove asd == NULL checks from ioctl handling At probe time isp_subdev_init_entities() sets pipe->asd to a non NULL value for all four (preview/vf/capture/capture_video) pipes by calling atomisp_init_subdev_pipe() for all 4 pipes. So it can never be NULL. Remove the redundant NULL checks.
