[PATCH 15/34] drivers/leds changes for SMBIOS and System Firmware

From: Prarit Bhargava
Date: Mon Jul 18 2011 - 09:14:39 EST


As part of the new SMBIOS and System Firmware code:

- Replace old dmi* structures and functions with new sysfw* and smbios*
structures and functions in individual drivers
- cleanup sysfw_id lookup tables
