From 161786259ca43dc4cad40755b48f868768577270 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 19 Jul 2020 10:15:55 -0600 Subject: usb: Drop dm.h header file This header file should not be included in other header files. Remove it and use a forward declaration instead. Also move the inline function out into a C file. We should not include C code in headers.
