From 3556dd408232e1d0dea7e24eea217a3d1185bfc0 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Wed, 16 Dec 2015 15:04:19 +0200 Subject: [PATCH] drm/i915/bios: fix format string of the VBT signature logging Specify the maximum number of letters to print from the potentially unterminated buffer, not the minimum. While at it, use sizeof instead of a magic number.
