It's somewhat expected that a commit introducing a new warning triggers
new warnings for the offending drivers.

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.

Best regards
Uwe
