From 4efaa6fbe1fd5e86ab2fee4cdcfc6873dab60716 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 4 Nov 2014 12:42:39 +0200 Subject: [PATCH] mmc: sdhci: Rename adma_desc to adma_table In preparation for 64-bit ADMA, rename adma_desc to adma_table. That is because members will be added for descriptor size and table size, so using adma_desc (which is the table) is confusing.
