Subject: sky2: Avoid rtnl_unlock without rtnl_lock
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2a40018984c5c9647df1c18489449a3a227d9136;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.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.
