From ec6ec9c6ca637f7678f1931cb835b2bb8ab6dfd2 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Thu, 2 Feb 2023 10:21:14 +0100 Subject: accel/ivpu: Fix old dma_buf api usage Update according to new dma-buf locking scheme. Remove redundant WARN_ON()'s, dma_buf functions internally have the same warnings already.
