From 4101f6879256720b30df712089a3df18565f9203 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 29 Feb 2016 15:25:34 -0700 Subject: dm: Drop the block_dev_desc_t typedef Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long and causes 80-column violations, rename it to struct blk_desc.
