From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] i2c: npcm7xx: Add check for platform_driver_register
[ Upstream commit 6ba12b56b9b844b83ed54fb7ed59fb0eb41e4045 ]
As platform_driver_register() could fail, it should be better
to deal with the return value in order to maintain the code
consisitency.
