[igt-dev] [PATCH i-g-t v4 02/10] lib/igt_chamelium: fix chamelium_port_set_edid docs

[Simon Ser]

There were two issues:

1. The documentation was wrong, the EDID ID 0 doesn't disable EDIDs, it just
   resets the EDID to Chamelium's default one.
2. My previous patch updating these docs missed the second line of the argument
   description. The result was that only reading the first line was fine, but
   reading both lines felt weird.
