From e2b01faedb34dc5153ded2798564c35f56f2be0d Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Fri, 11 Sep 2026 14:43:56 +0200 Subject: [PATCH] drm/panic: Return -EINVAL if font is not available Font lookup does not allocate memory. Hence reporting ENOMEM on failed lookups is misleading. Report EINVAL instead.
