Subject: drm/simpledrm: Use offset-adjusted shadow-plane mapping
Git-commit: 8b9b88b94b96dbd9aad888ac2c730a9e3ffa4ec3
Patch-mainline: v5.15-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
For framebuffers with non-zero offset fields, shadow-plane helpers
provide a pointer to the first byte of the contained data. Use it in
simpledrm.
