From 9e191b22c91873c09c722d7f956ab9f3276f9a37 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 4 Aug 2011 10:47:40 +0100 Subject: dt: remove of_alias_get_id() reference of_alias_get_id() is broken and being reverted. Remove the reference to it and replace with a single incrementing id number. There is no risk of regression here on the imx driver since the imx change to use of_alias_get_id() is commit 22698aa2, "serial/imx: add device tree probe support" which is new for v3.1, and it won't get used unless CONFIG_OF is enabled and the board is booted using a device tree. A single incrementing integer is sufficient for now.
