If your out of tree driver is using the kernel build system, it should
already be doing the depmod invocation.

If it's not using the kernel build system, then you can invoke depmod
manually, like the nvidia-driver package is doing in Buildroot:

  $(HOST_DIR)/sbin/depmod -a -b $(TARGET_DIR) $(LINUX_VERSION_PROBED)

But really, to give you more details, we need to know which out of tree
driver we're talking about, see how it has been packaged in Buildroot,
and where it is installed in the root filesystem.

Best regards,

Thomas
