This patch has hit linux-next in the form of coommit 3fc3895e4fe1
(twl4030_charger: correctly handle -EPROBE_DEFER from
devm_usb_get_phy_by_node) and kernelci.org found a regression on
omap3-beagle-xm[1].  Bisecting[2] this boot failure pointed at this
commit, and I verified that reverting it on top of next-20150827 gets
the board booting again.  I haven't debugged any further.
