From 0796e439c5cc4ceeb84e08479c5ee1a4ebab5549 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Thu, 8 Jun 2017 15:27:45 +0200 Subject: mmc: core: Clarify code for sending CSD To make the code more consistent and to increase readability, add an mmc_spi_send_csd() function, which gets called from mmc_send_csd() in case of SPI mode.
