Are the methods for checking and removing drivers in the linux kernel parallel across multiple devices?

Can anyone shed some light on a series of transforms .probe

and .remove

drivers <? t →

For example, if there are 10 PCIe cards connected to the server and there is a generic driver to detect (probe) these 10 devices, what is the name of the probe function? Is it being called in parallel for all devices, or is it done one after the other - which means the second probe call won't happen until the first probe call for the first device returns?
