[media] exynos4-is: Copy timestamps from M2M OUTPUT to CAPTURE buffer queue
Add copying of buffer timestamps and set the timestamp_type to V4L2_BUF_FLAG_TIMESTAMP_COPY to avoid warnings about UNDEFINED timestamp type like: WARNING: at drivers/media/v4l2-core/videobuf2-core.c:2042 vb2_queue_init+0xe0/0x18c() Modules linked in: [<c0016ef0>] (unwind_backtrace+0x0/0x13c) from [<c0029b3c>] (warn_slowpath_common+0x54/0x64) [<c0029b3c>] (warn_slowpath_common+0x54/0x64) from [<c0029b68>] (warn_slowpath_null+0x1c/0x24) [<c0029b68>] (warn_slowpath_null+0x1c/0x24) from [<c03b7018>] (vb2_queue_init+0xe0/0x18c) [<c03b7018>] (vb2_queue_init+0xe0/0x18c) from [<c03b4e08>] (v4l2_m2m_ctx_init+0xa0/0xc4) [<c03b4e08>] (v4l2_m2m_ctx_init+0xa0/0xc4) from [<c03ca6c4>] (fimc_m2m_open+0x130/0x1f8) [<c03ca6c4>] (fimc_m2m_open+0x130/0x1f8) from [<c03a5dd4>] (v4l2_open+0xac/0xe8) [<c03a5dd4>] (v4l2_open+0xac/0xe8) from [<c0113920>] (chrdev_open+0x9c/0x158) [<c0113920>] (chrdev_open+0x9c/0x158) from [<c010e488>] (do_dentry_open+0x1f8/0x280) [<c010e488>] (do_dentry_open+0x1f8/0x280) from [<c010e600>] (finish_open+0x34/0x50) [<c010e600>] (finish_open+0x34/0x50) from [<c011cc58>] (do_last+0x5bc/0xc00) [<c011cc58>] (do_last+0x5bc/0xc00) from [<c011d34c>] (path_openat+0xb0/0x484) [<c011d34c>] (path_openat+0xb0/0x484) from [<c011d824>] (do_filp_open+0x30/0x84) [<c011d824>] (do_filp_open+0x30/0x84) from [<c010e0f8>] (do_sys_open+0xe8/0x170) [<c010e0f8>] (do_sys_open+0xe8/0x170) from [<c000f040>] (ret_fast_syscall+0x0/0x30) Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
