Subject: [PATCH] mmc: sd: warn if card stays busy during init
Date: Fri, 23 May 2014 16:15:03 +0200	[thread overview]
Message-ID: <1400854503-9945-1-git-send-email-johanru@axis.com> (raw)

The initialization of some SD-cards fails because the card never
leaves the busy state. Aid trouble shooting by indicating this in the
kernel log.
