From 2dfb579c7da171f6153cd58e8fbf7dcfe684778d Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 15 Oct 2010 12:21:01 +0200 Subject: mmc: sdhci: introduce get_ro private write-protect hook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some controllers handle their write-protection differently. Introduce a callback to be able to handle it, ensuring the same locking takes place for it. Rename the status variable to make it more obvious why the read from the registers needs to be inverted.
