From: Hans Verkuil Date: Mon, 14 Oct 2024 15:06:37 +0000 (+0200) Subject: media: samples: v4l2-pci-skeleton.c: drop vb2_ops_wait_prepare/finish X-Git-Tag: v6.13-rc1~149^2~84 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=d020ca11a816a99f87f2d186e137a9fb2341adb3;p=linux-block.git media: samples: v4l2-pci-skeleton.c: drop vb2_ops_wait_prepare/finish Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks.
