From: Alexandre Courbot Date: Wed, 8 Jun 2016 08:32:39 +0000 (+0900) Subject: drm/nouveau/gr/gf100: handle secure boot errors X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7fcab839015d67b35de0b7031ed074e3ebe708f8;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/nouveau/gr/gf100: handle secure boot errors Handle and propagate secure boot errors. Failure to do so results in Nouveau incorrectly believing init has succeeded and a completely black display during boot. If we propagate the error, GR init will fail and the user will at least have a working display.
