Subject: powerpc/iseries: use DECLARE_COMPLETION_ONSTACK for non-constant completion
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c3a66359398028cd8e5f32611950dc7dc32ea2f2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

powerpc/iseries: use DECLARE_COMPLETION_ONSTACK for non-constant completion

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