Yes, probe deferral is still used in the controller. For example, dwc2 every time use defer probe to wait phy probe complete. However since they are in the same folder, and we already know the sequence, is it better to change the sequence to make it quicker.

Since phy is definitely used usb controller, load the phy earlier rather than using defer probe to make boot time shorter. Signed-off-by: Zhangfei Gao <zhangfei.gao@linaro.org> --- drivers/usb/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
