6.7-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 9ec9109cf9f611e3ec9ed0355afcc7aae5e73176 ]
The pad local variable in the media_pipeline_explore_next_link() function is used to store the pad through which the entity has been reached. Rename it to origin to reflect that and make the code easier to read. This will be even more important in subsequent commits when expanding the function with additional logic.
