Subject: [PATCH 5.19 398/717] media: amphion: dont change the colorspace reported by decoder.

From: Ming Qian <ming.qian@....com>

[ Upstream commit 61c2698ee60630c6a7d2e99850fa81ff6450270a ]

decoder will report the colorspace information
which is parsed from the sequence header,
if they are unspecified, just let application to determine it,
don't change it in driver.
