If anyone has any objections, please let me know. ------------------ From: Christophe JAILLET [ Upstream commit b36fb50701619efca5f5450b355d42575cf532ed ] If an error occurs after a successful phy_init() call, then phy_exit() should be called. Add the missing call, as already done in the remove function.
