From c692696fc51c5acee555b94d391d328510b557c8 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Wed, 6 Dec 2023 13:35:33 +0200 Subject: [PATCH] media: saa6752hs: Don't set format in sub-device state For the purpose of setting old non-pad based sub-device try format as a basis for VIDIOC_TRY_FMT implementation, there is no need to set the format in the sub-device state. Drop the assignment to the state, which would result in a NULL pointer dereference.
