From abfe8afe88d6d8219602659f44981411e1daeb1d Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 5 May 2014 10:40:15 -0600 Subject: ums: move IO support code to common location There's nothing Samsung-/board-specfic about the implementation of ums_init(). Move the code into cmd_usb_mass_storage.c, so that it can be shared by any user of that command.
