What I was saying as with SAS and FC, our firmware sends events to the driver which tells when devices are pulled or pushed. When that event occurs, we call functions in the transport layers that handle hotpluging the device automatically, that doesn't require an enduser to echo something into the /proc or /sysfs. As for SPI, there are not events that notifiy the driver when a device is pulled or pushed. Therefore you will need to do what you suggested.
