The patch titled mmc: add Extended CSD as a device attribute has been removed from the -mm tree. Its filename was mmc-add-extended-csd-as-a-device-attribute.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mmc: add Extended CSD as a device attribute From: Adrian Hunter <ext-adrian.hunter@xxxxxxxxx> Extended CSD is a MMC card register. The Card Identification (CID) register and the Card-Specific Data (CSD) register are already device attributes. As increasingly interesting fields are being added to Extended CSD, it seems reasonable to add it too. Note that SD cards do not have an Extended CSD register, so it is MMC only.
