Subject: [PATCH v2 1/2] edid-decode: add function to enable usage as a library
Date: Thu, 13 Feb 2020 06:39:02 -0500 [thread overview]
Message-ID: <20200213113903.23994-1-imirkin@alum.mit.edu> (raw)
This is helpful for an emscripten setup, as there's no great way to
reinitialize the object from scratch.
