From 9f38617da4ed21a14d97cd0d920023e8fb3d3fd6 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 15 Oct 2025 10:53:33 +0300 Subject: [PATCH] media: dw100: Drop unneeded v4l2_m2m_get_vq() NULL check The v4l2_m2m_get_vq() function never returns NULL. In the set format handler, the check may have been intended to catch invalid format types, but that's not needed as the V4L2 core picks the appropriate VIDIOC_S_FMT ioctl handler based on the format type, so the type can't be incorrect. In the get format handler, the return value is not used for any purpose other than the NULL check, which was therefore probably intended to catch invalid format types. That's not needed for the same reason as in the set format handler. Drop the unneeded return value checks and, as the function has no side effect, the unneeded function call as well.
