The data written to the chardev is a pulse/space sequence of integer
values. Pulses and spaces are only marked implicitly by their position.
The data must start and end with a pulse, therefore, the data must
always include an uneven number of samples. The write function must
block until the data has been transmitted by the hardware. If more data
is provided than the hardware can send, the driver returns ``EINVAL``.

doc-rst: linux_tv: Error codes should be const All error codes should be const. Most are, but there are lots of places where we forgot to add <constant> at the DocBook. Fix those via this small script: for i in $(git grep -lE "\s+E[A-Z]+\b" Documentation/linux_tv/); do perl -ne 's,([^\`])\b(E[A-Z]+)\b,\1``\2``,g; print $_' <$i >a && mv a $i; done As there are false positives, we needed to merge only the changes that make sense, skipping the c blocks and skipping things like EDID, EN, ETS that were also converted by the above code.
