From 78fba982db768fd2cd3f05b03ea2b2b13af1cfbb Mon Sep 17 00:00:00 2001 From: Bin Liu Date: Mon, 21 May 2018 08:42:09 -0500 Subject: [PATCH] usb: musb: merge musbhsdma.h into musbhsdma.c Now Blackfin support is removed, header musbhsdma.h is only included in musbhsdma.c. So let's merge the content in musbhsdma.h to musbhsdma.c and delete musbhsdma.h.
