Subject: [PATCH] powerpc: Initialise hvlpevent_queue.lock correctly
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bd6ef57e08d6cce32e93f9fc7b93d361b6a7884f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] powerpc: Initialise hvlpevent_queue.lock correctly

When I changed the hvlpevent_queue code to use a spinlock instead of a
custom atomic (719d1cd86780c156f954fc34f34481adac197aec) I didn't
initialise the lock anywhere, oops.
