Subject: [PATCH 4/9] mmc: core: Move mmc_flush_cache() from core.c to mmc_ops.c
Date: Thu,  8 Jun 2017 15:27:40 +0200	[thread overview]
Message-ID: <1496928465-25004-5-git-send-email-ulf.hansson@linaro.org> (raw)
In-Reply-To: <1496928465-25004-1-git-send-email-ulf.hansson@linaro.org>

The mmc_flush_cache() is a eMMC specific function, let's move it to
mmc_ops.c to make that clear.
