From ce19d974018273c8f69d98b7139e7fef822cc02a Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 5 May 2014 10:40:11 -0600 Subject: [PATCH] ums: support block devices not MMC devices The USB Mass Storage function could equally well support a SATA device as support an MMC device. Update struct ums to contain a block device descriptor, not an MMC device descriptor.
