[PATCH] platform: Do not complain for platform_data added by platform_device_add_data()

From: Atsushi Nemoto
Date: Thu Apr 16 2009 - 09:50:34 EST


The commit ce21c7bc ("driver core: fix passing platform_data") added
an error message "foo: use which platform_data?", but this is normal
if platform_device_add_data() was used.

Do not print the error message if pdev->platform_data and
pdev->dev.platform_data have same value.
