What is the reason to remove that device in the first place? Like is this really a valid scenario? I really don't know when a device is removed and if its remove, will it still be there or is it rather a hot-plug type and rebinding it won't work anyways.
Did you get this to crash under any circumstance other than using the 'unbind' command?
Nope, thus I was curious about that comment in dsa_port_stop(). Someone (Alex, Claudiu maybe?) must have something in mind when writing about it. But I couldn't figure out in which case a device is removed.
I'm pretty sure that the checks that are in place now were once written so that the sandbox tests would pass. If they still do, we should be fine.
You can run the sandbox tests using:
make sandbox_defconfig NO_SDL=1 make -j 8 NO_SDL=1 ./u-boot -d ./arch/sandbox/dts/test.dtb setenv ethact swp0 ping 1.2.3.5 ut dm dsa_probe ut dm dsa ut dm ut dm net_retry
