From 291ee9d5da535f8c72408850a413074c4719c8d3 Mon Sep 17 00:00:00 2001 From: Mårten Lindahl Date: Mon, 16 Aug 2021 17:30:54 +0200 Subject: mmc: core: Update ->card_busy() callback comment MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit According to SD specification checking state of DAT0 only, is enough while polling for card busy completion. Let's update the comment in the header file to correct this, as the comment says DAT[0:3].
