From 241999bf4c0dd75d300ceee46f7ad28b3a39fe97 Mon Sep 17 00:00:00 2001 From: Prasad J Pandit Date: Tue, 28 Feb 2017 12:08:15 +0000 Subject: [PATCH] sd: sdhci: Remove block count enable check in single block transfers In SDHCI protocol, the 'Block count enable' bit of the Transfer Mode register is relevant only in multi block transfers. We need not check it in single block transfers.
