From 7c2bc34ab926447f1b329a57669adfce76eafc3c Mon Sep 17 00:00:00 2001 From: Srinivasan Shanmugam Date: Wed, 20 Mar 2024 14:13:54 +0530 Subject: drm/amdgpu: Fix format character cut-off issues in amdgpu_vcn_early_init() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reducing the size of ucode_prefix to 25 in the amdgpu_vcn_early_init function. This would ensure that the total number of characters being written into fw_name does not exceed its size of 40.
