Hi Hans, I noticed there are two s_std ops in core and video for output. And some drivers call video->s_std_out and then core->s_std in their S_STD iotcl. Could anyone share me the story why we have s_std_output/g_std_output/g_tvnorms_output ops in video instead of making use of s_std/g_std in core?
