Subject: twl4030_charger: correctly handle -EPROBE_DEFER from devm_usb_get_phy_by_node
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3fc3895e4fe17ee92ae1d1bb9f04da6069e8c370;p=linux-beck.git

twl4030_charger: correctly handle -EPROBE_DEFER from devm_usb_get_phy_by_node

Now that twl4030_bci_probe can safely return -EPROBE_DEFER,
do so when devm_usb_get_phy_by_node returns that error.
