From 05930cf1e5c5d7d526e492cfe0f0bb3116bc29de Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 6 Jul 2020 20:36:31 +0200 Subject: [PATCH] media: ti-vpe: cal: Read hardware revision earlier during probe Read the hardware revision and info right after allocating resources, as there's no need to delay doing so until all initialization is complete.
