From 012994f4fa5fc7663b51fa921c85c0a352339b24 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 15 Oct 2010 12:21:02 +0200 Subject: [PATCH] mmc: sdhci_pltfm: pass more data on custom init call MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The custom init call may need more data to perform its job, so we pass it a pointer to pdata, too. Also, always use the platform_id specific data even if platform_data is present. Doing that, platform_data can additionally be parsed by init() for board-specific information (via sdhci->mmc->parent). (Note: the old behaviour was that you could override the platform_id specific data with your own. However, one can still do this by using the "sdhci" id instead of "sdhci-".)
