Subject: usb: chipidea: ci13xxx_imx: check if 'data->phy_np' is not NULL
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b35d73b62d2cc245ef32d396535e452c70681bfa;p=karo-tx-linux.git

usb: chipidea: ci13xxx_imx: check if 'data->phy_np' is not NULL

Similarly as it is done in ci13xxx_imx_remove(), only calls of_node_put if
data->phy_np is not NULL.
