Subject: [PATCH] drm/nouveau/secboot/gm20b: initialize pointer in gm20b_secboot_new()
Git-commit: 3613a9bea95a1470dd42e4ed1cc7d86ebe0a2dc0
Patch-mainline: v5.6-rc1
References: bsc#1051510
We accidentally set "psb" which is a no-op instead of "*psb" so it
generates a static checker warning. We should probably set it before
the first error return so that it's always initialized.
Fixes: 923f1bd27bf1 ("drm/nouveau/secboot/gm20b: add secure boot support")
