From a88340dfcf8a34cf7fe000c619d01e1d0f0a442a Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 11 Nov 2014 10:46:20 -0700 Subject: [PATCH] dm: fdt: Correct handling of aliases with embedded digits Since we scan from left to right looking for the first digit, "i2c0" returns 2 instead of 0 for the alias number. Adjust the code to scan from right to left instead.
