And looking for platform_driver_probe() in recent changesets, I found
a few more:

drivers/input/touchscreen/atmel-wm97xx.c atmel_wm97xx_probe
drivers/input/touchscreen/mc13783_ts.c mc13783_ts_probe
drivers/input/serio/at32psif.c psif_probe
drivers/input/mouse/amimouse.c amimouse_probe

Interestingly, in drivers/input/misc/twl4030-pwrbutton.c you did make
platform_driver.probe point to twl4030_pwrbutton_probe().
But that one is also broken, as twl4030_pwrbutton_probe() is marked __init,
which is no longer correct.

Still, setting up platform_driver.probe and removing __init from all probe
functions is not the right thing to do, as this make (non-__init) kernel code
size bigger, while none of these devices are hotpluggable and thus cannot
appear after bootup. That's why we have platform_driver_probe() in the
first place. So I think all of this should be reverted for non-hotpluggable
drivers.

Thank you for explaining this.
I am sorry for the trouble.
