There are some more offenders than these. A quick look into these three shows that the warning is a false positive (i.e. I don't expect that a driver follows a link to a discarded function). To fix this you either need a commit like 141626dbc2e6 ("rtc: sh: Mark driver struct with __refdata to prevent section mismatch warning") (if you really want continue using module_platform_driver_probe()), or modernize the driver (at the cost of a slightly increased memory footprint) with something like: 1865913dd590 ("media: meson-ir-tx: Drop usage of platform_driver_probe()") Addressing these is on my todo list, but not at it's top.
