Subject: [BACKPORT 4.4.y 17/25] mmc: core: don't try to switch block size for dual rate mode
Date: Fri, 22 Mar 2019 16:44:08 +0100	[thread overview]
Message-ID: <20190322154425.3852517-18-arnd@arndb.de> (raw)
In-Reply-To: <20190322154425.3852517-1-arnd@arndb.de>

From: Ziyuan Xu <xzy.xu@rock-chips.com>

Per spec, block size should always be 512 bytes for dual rate mode,
so any attempts to switch the block size under dual rate mode should
be neglected.
