From bd1a7e3034006ec121d35d745fd455212a56f7fd Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Fri, 5 Oct 2012 13:17:39 +0000 Subject: FAT: check for partition 0 not 1 for whole-disk fs The recent switch to use get_device_and_partition() from do_fat_ls() broke the ability to access a FAT filesystem directly on a whole device; FAT only works within a partition on a device. This change makes e.g. "fatls mmc 0:0" work; explicitly requesting partition ID 0 is something that get_device_and_partition() fully supports. However, fat_register_device() expects partition ID 1 to be used in the full-disk case; partition ID 1 was previously implicitly specified when the user didn't actually specify a partition ID. Update fat_register_device() to expect the correct ID. This change does imply that if a user explicitly executes "fatls mmc 0:1" then this will fail, and may be a change in behaviour. Note that this still prevents "fatls mmc 0:auto" from working. The next patch will fix that.
