Subject: drm/radeon: remove redundant assignment to reg
Git-commit: ee2016b4b5bb70483e1c06218e7b6288704284cb
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 pointer reg is being assigned a value that is not read, the
exit path via label 'out' never accesses it. The assignment is
redundant and can be removed.
Cleans up clang scan build warning:
drivers/gpu/drm/radeon/radeon_object.c:570:3: warning: Value
stored to 'reg' is never read [deadcode.DeadStores]
