Subject: sky2: Avoid rtnl_unlock without rtnl_lock
X-Git-Tag: 2.1b_release~8486^2~256
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2a40018984c5c9647df1c18489449a3a227d9136;p=platform%2Fkernel%2Fkernel-mfld-blackbay.git

sky2: Avoid rtnl_unlock without rtnl_lock

Make sure we always call rtnl_lock before going down the
error path in sky2_resume, which unlocks the rtnl lock.
