From 5a0193d818162a4d12a8c9b48fa7dbd006a95b3b Mon Sep 17 00:00:00 2001 From: Nicolas Dufresne Date: Fri, 13 May 2022 22:29:13 +0200 Subject: [PATCH] media: rkvdec: Move H264 SPS validation in rkvdec-h264 No functional change, this moves H264 specific validation into the H264 specific code. This is in preparation of improving this validation and reusing it when VIDIOC_STREAMON is called.
