[FFmpeg-devel] [PATCH v2 1/6] avutil/csp: fix documentation of av_csp_trc_function

[Niklas Haas]

From: Niklas Haas <git at haasn.dev>

This explanation was inaccurate and highly misleading. The new wording is taken
more or less directly from ITU-T H.273, and also matches my understanding of
these functions.
