From 0935dbf4c9d97574d04e6d2e1bda2abd7135c073 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Sat, 19 Feb 2022 17:08:41 -0600 Subject: [PATCH] usb: ehci-omap: Drop dead code omap_ehci_hcd_stop appears to be dead code, and omap_ehci_hcd_init is only called by the probe function, so it can be static to that function. Remove both from the header along with some additional checking for DM_USB.
