Subject: mISDN: use DECLARE_COMPLETION_ONSTACK for non-constant completion
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=01a1e7ec6c3769dc7c5fde23ebc253c6be5f68eb;p=openwrt%2Fstaging%2Fblogic.git

mISDN: use DECLARE_COMPLETION_ONSTACK for non-constant completion

The _ONSTACK variant should be used for on-stack completion,
otherwise it will break lockdep.
