[ Upstream commit f56e67f0a880a5b795cdb5f62614aafe264c5304 ]
The commit 1290a958d48e ("usb: phy: propagate __of_usb_find_phy()'s error on failure") changed the condition to return -EPROBE_DEFER to host driver. Originally the Tegra host driver depended on the returned -EPROBE_DEFER to get the phy device later when booting. Now we have to do that explicitly.
