Commit 40dcd0e ("usb: chipidea: add PTW, PTS and STS handling") introduced
the following code to the ci_hdrc_probe() function:
+ if (!dev->of_node && dev->parent)
+ dev->of_node = dev->parent->of_node;
This inadvertently associates the ci_hdrc device with the ci_hdrc_imx
driver (which created the ci_hdrc device in the first place).
This results in ci_hdrc_imx_probe() being run for the ci_hdrc device
if ci_hdrc_probe() fails for some reason.
ci_hdrc_imx_probe() will happily create a new ci_hdrc platform_device
whose probing will likewise fail and trigger a new invocation of
ci_hdrc_imx_probe() ... ad nauseam.
