From 3362177fe1b7c23ee8497ee720ab4d6f6ba0b840 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marc-Andr=C3=A9=20H=C3=A9bert?= Date: Mon, 31 Jan 2011 12:31:24 -0500 Subject: [PATCH] mmc: Fix the block device read only flag While the MMC handled the card's read only flag correctly on open, it did not setup the flag in the allocated disk structure. The consequence being that probing the /sys/class/block/mmcblkX/ro attribute always reported 0.
