1、mipi dsi 工作在MIPI_DSI_MODE_VIDEO_SYNC_PULSE 4 lanes, MIPI_DSI_FMT_RGB888时，输出图像显示异常，最左边红色框中的图案应该显示在最右边，具体图片如下文
2、使用modetest 工具测试，测试命令：modetest -M rockchip -s 88@61:1920x720

1920x720异常

selftests/bpf: Test bpf_mprog query API via libbpf and raw syscall
f9b0879 
Add a new test case which performs double query of the bpf_mprog through
libbpf API, but also via raw bpf(2) syscall. This is testing to gather
first the count and then in a subsequent probe the full information with
the program array without clearing passed structs in between.

selftests/bpf: Test query on empty mprog and pass revision into attach

Add a new test case to query on an empty bpf_mprog and pass the revision
directly into expected_revision for attachment to assert that this does
succeed.
