From eff68a9e24c3a73d37d481a968c575d60985049f Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Mon, 4 Jul 2022 09:49:30 +0100 Subject: [PATCH] media: mediatek: vcodec: Initialize decoder parameters for each instance [ Upstream commit fe3d651627d61210c6905339e5281d3b9db75033 ] The decoder parameters are stored in each instance's context data. This needs to be initialized per-instance, but a previous fix incorrectly changed it to only be initialized for the first opened instance. This resulted in subsequent instances not correctly signaling the requirement for the Requests API. Fix this by calling the initializing function outside of the v4l2_fh_is_singular() conditional block.
