From b52b88ce5bd68e9f6ce4f01d2306e61ce34fc5a0 Mon Sep 17 00:00:00 2001 From: Michael Tretter Date: Mon, 26 Nov 2018 13:01:24 -0500 Subject: media: v4l2-pci-skeleton: replace vb2_buffer with vb2_v4l2_buffer Commit 2d7007153f0c ("[media] media: videobuf2: Restructure vb2_buffer") replaced vb2_buffer with vb2_v4l2_buffer in all v4l2 drivers. The restructuring skipped the v4l2-pci-skeleton, probably because it resides outside the drivers directory. The v4l2_buf_ops assume that the passed buffer is a vb2_v4l2_buffer. This is not the case if the skel_buffer is based on vb2_buffer instead of vb2_v4l2_buffer. Replace vb2_buffer with vb2_v4l2_buffer in the skeleton to make sure that future drivers that are based on the skeleton use vb2_v4l2_buffer.
