From 07b240411f1e7528ed36e09979f40ccf4b844c8c Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Fri, 11 Jan 2013 17:03:52 +0000 Subject: [PATCH] mmc: dw_mmc: exynos: Remove code for wp-gpios The exynos code claimed the write protect with devm_gpio_request() but never did anything with it. That meant that anyone using a write protect GPIO would effectively be write protected all the time. The handling for wp-gpios belongs in the main dw_mmc driver and has been moved there.
