[PATCH v6 1/4] drm/bridge/analogix/anx78xx: Drop ID table

From: Biju Das
Date: Thu Aug 31 2023 - 04:09:56 EST


The driver has an ID table, but it uses the wrong API for retrieving match
data and that will lead to a crash, if it is instantiated by user space or
using ID. From this, there is no user for the ID table and let's drop it
from the driver as it saves some memory.
