commit 74f5f42c35daf9aedbc96283321c30fc591c634f Author: Sui Jingfeng sui.jingfeng@linux.dev Date: Wed May 8 02:00:00 2024 +0800

 drm/drm-bridge: Drop conditionals around of_node pointers
 
 [ Upstream commit ad3323a6ccb7d43bbeeaa46d5311c43d5d361fc7 ]
 
 Having conditional around the of_node pointer of the drm_bridge structure
 is not necessary, since drm_bridge structure always has the of_node as its
 member.
 
 Let's drop the conditional to get a better looks, please also note that
 this is following the already accepted commitments. see commit d8dfccde2709
 ("drm/bridge: Drop conditionals around of_node pointers") for reference.

Hi Sasha,

this breaks the x86_64 build for me.

AFAICT this patch cannot work without commit d8dfccde2709de4327c3d62b50e5dc012f08836f "drm/bridge: Drop conditionals around of_node pointers", but that commit is only present in Linux >= 6.7.

This issue affects the 6.6, 6.1 and 5.15 branches.

Regards Pascal
