Subject: [PATCH] mmc: host: Update card_busy callback info
Date: Mon, 16 Aug 2021 17:30:54 +0200 [thread overview]
Message-ID: <20210816153054.24082-1-marten.lindahl@axis.com> (raw)
According to SD specification checking state of DAT0 only is enough for
polling card busy signal. Header file comment says DAT[0:3]. Fix this.
