This issue has been fixed already, the fixes are available in the master
branch of git://linuxtv.org/media_stage.git:

e49b1e1958b4 media: nxp: ignore unused suspend operations
9829ed20b019 media: nxp: imx8-isi: fix buiding on 32-bit

Mauro, can you please include those two fixes in your next pull request
for v6.4 ?
