I will address your comment and send new patch. My rationale for removing the scanning from dm_extended_scan_fdt() was based on the order of the scan. Why do you think removing the scan from dm_extended_scan_fdt() is better? --Thiru

Subnodes under "/firmware" node are scanned twice in dm_scan_fdt_node and dm_extended_scan_fdt. This patch removes the double scanning. This reverts commit 1712ca21924bff678f19fd3141f435408d23bdbf.
