Subject: [REGRESSION] NULL pointer dereference drm_dp_add_payload_part2
Date: Wed, 07 Feb 2024 09:45:56 +0100	[thread overview]
Message-ID: <38c253ea42072cc825dc969ac4e6b9b600371cc8.camel@ruhr-uni-bochum.de> (raw)

Hello,

54d217406afe250d7a768783baaa79a035f21d38 fixed an issue in
drm_dp_add_payload_part2 that lead to a NULL pointer dereference in
case state is NULL.

The change was (accidentally?) reverted in
5aa1dfcdf0a429e4941e2eef75b006a8c7a8ac49 and the problem reappeared.

The issue is rather spurious, but I've had it appear when unplugging a
thunderbolt dock.
