From f795d282adfbba87fc93653fd169fbc492aa80b1 Mon Sep 17 00:00:00 2001
From: Dan Carpenter <dan.carpenter@oracle.com>

Subject: video: fbdev: savagefb: make a variable local
Git-commit: 0f8a1cae923670b1cabb9a8f416271344159bd50
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
The "edid" struct member is only used during probe() and it's freed
right away. There is no point in storing a freed pointer for the
whole life of the driver.
