Subject: drm/omap: fix NULL but dereferenced coccicheck error
Git-commit: 8f2a3970c969d0d8d7289a4c65edcedafc16fd92
Patch-mainline: v5.19-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
Fix the following coccicheck warning:
./drivers/gpu/drm/omapdrm/omap_overlay.c:89:22-25: ERROR: r_ovl is NULL
but dereferenced.
Here should be ovl->idx rather than r_ovl->idx.
Fixes: e02b5cc9e898ad ("drm/omap: Add a 'right overlay' to plane state")
