From 79d867c2e683f7080a8724a54a4a12ac0ce1f837 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 5 May 2016 16:59:12 -0700 Subject: usb: ehci-mx6: allow board_ehci_hcd_init to fail There could be runtime determined board specific reason why a EHCI initialization fails (e.g. ENODEV if a Port is not available). In this case, properly return the error code. While at it, that function (board_ehci_hcd_init) has actually two documentation blocks... Use the correct function name for the documentation block of board_usb_phy_mode.
