USB: g_dnl: Change device class
The USB Mass Storage (ums) works in Windows, Linux and OS X (EL Capitan). But, not in OS X (Yosemite). By applying the said patch, it extends the ums support. Signed-off-by: John Tobias <john.tobias.ph@gmail.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> Test HW: Odroid XU3 (./test/py UMS + DFU tests) Tested-by: John Tobias <john.tobias.ph@gmail.com> Linux: - Run ums to expose all my eMMC partition - shows all correctly - Run ums to expose only 1 partition of my eMMC - show correctly Windows: - Run ums to expose all my eMMC partition - it detects but it prompts, if I want to format it (due to a non windows partition) - Run ums to expose only the FAT32 partition - it show the partition correctly.
