Subject: [PATCH] Hotplug: Make dev->bus checking consistent
From: Alexander Nyberg <alexn@dsv.su.se>
To: greg@kroah.com
Date: Sat, 26 Feb 2005 13:38:51 +0100

Earlier in the same function dev->bus is checked before dereferenced,
make consistent although I honestly don't know if dev->bus could
ever be NULL
