#     Revert "media: dvb header files: move some headers to staging"
#     
#     This reverts commit 819fbd3d8ef36c09576c2a0ffea503f5c46e9177.
#     
#     It turns out that some user-space applications use these uapi header
#     files, so even though the only user of the interface is an old driver
#     that was moved to staging, moving the header files causes unnecessary
#     pain.
#     
#     Generally, we really don't want user space to use kernel headers
#     directly (exactly because it causes pain when we re-organize), and
#     instead copy them as needed.  But these things happen, and the headers
#     were in the uapi directory, so I guess it's not entirely unreasonable.
