From 14b04c6a50f80f4560152486a47de97754e6466f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Micha=C5=82=20Miros=C5=82aw?= Date: Mon, 14 Aug 2017 22:00:24 +0200 Subject: [PATCH] mmc: sdhci-tegra: use generic sdhci_set_bus_width() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Now that sdhci_set_bus_width() supports 8-bit bus widths based on the MMC_CAP_8_BIT_DATA capability flag, replace the tegra version with the generic sdhci version.
