[FFmpeg-devel] [PATCH 2/2] avcodec/pngenc: fix mDCv typo

[Leo Izen <leo.izen@gmail.com>]

When mDCv support was added, there was a typo in both variable names
and also the MKTAG itself, incorrectly listing it as mDVc. The tag name
stands for Mastering Display Color Volume so mDCv is correct.

Typo originally introduced in 78949041417caaef0c82b2b23d7defdd88aa2378.
