From b0284de05e07d56ff7de154d0c9263788755f5eb Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 30 Nov 2012 10:09:42 +0000 Subject: ab8500_bm: Rename battery management platform data to something more logical The platform specific battery management configuration data structure is currently called 'bat' short for 'battery'; however, it contains information for all components of the battery management group, rather than information pertaining to the battery itself - there are other structures for that. So, in keeping with its structure namesake 'abx500_bm_data', we rename it to 'bm' here. Using similar logic, we're also renaming 'bmdevs_of_probe' to the more device specific 'ab8500_bm_of_probe'.
