Subject: ppp: Do not free not yet unregistered net device.
X-Git-Tag: v2.6.26-rc3~65^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4b95ede6f6116ae1c0ed9605ec97d856c4814569;p=platform%2Fkernel%2Flinux-stable.git

ppp: Do not free not yet unregistered net device.

An error path in ppp_create_interface() lacks one and may
BUG in free_netdev() checking for proper dev->reg_state.
