From 3373755a415c9c8024d26cf32fd812a8cdb82541 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Mon, 5 Dec 2016 22:39:30 +0200 Subject: [PATCH] drm/virtio: annotate virtio_gpu_queue_ctrl_buffer_locked virtio_gpu_queue_ctrl_buffer_locked is called with ctrlq.qlock taken, it releases and acquires this lock. This causes a sparse warning. Add appropriate annotations for sparse context checking. Signed-off-by: Michael S.
