From be76f150bcadec1707e3718b0750a8b2261b3c20 Mon Sep 17 00:00:00 2001 From: Stanimir Varbanov Date: Wed, 16 Jan 2019 14:48:47 -0200 Subject: [PATCH] media: venus: vdec: allow bigger sizeimage set by clients In most of the cases the client will know better what could be the maximum size for compressed data buffers. Change the driver to permit the user to set bigger size for the compressed buffer but make reasonable sanitation.
