6.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jackson.lee jackson.lee@chipsnmedia.com
commit 6bae4d5053da634eecb611118e7cd91a677a4bbf upstream.
When a decoder instance is created, the W5_CMD_ERR_CONCEAL register should be initialized to 0. Otherwise, gray color is occasionally displayed on the screen while decoding.
