This is slightly misleading because that manual MODULE_ALIAS is there for legacy reasons and created that alias to bind against a platform device created from board files back in the day. Depending on how I interpret the commit message, it also sounds like you're suggesting that the OF core will automatically add this alias. However, what the OF core adds is an alias based on the OF device ID table, which is completely different. We don't support board files anymore and to my knowledge the aliases generated from the OF device ID table are enough to have the driver autoloaded, so this patch is correct. Perhaps make it clearer in the commit message why this is no longer needed.
