From 1d32c26f28d6e25f447b8ba40440c7d228ed4006 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Mon, 3 Jun 2013 17:17:45 +0100 Subject: sd/sdhci:ADMA: fix interrupt The end of transfer check was occurring and potentially returning before the interrupt flag was checked. This means the interrupt will be missed if it occurs on the last packet. Fix by checking for the interrupt before checking for the end of transfer.
