Subject: [PATCH] drm/nouveau/kms/nv50: hide unused variables
Date:   Mon, 25 Sep 2023 17:59:24 +0200

From: Arnd Bergmann <arnd@arndb.de>

After a recent change, two variables are only used in an #ifdef:

drivers/gpu/drm/nouveau/dispnv50/disp.c: In function 'nv50_sor_atomic_disable':
drivers/gpu/drm/nouveau/dispnv50/disp.c:1569:13: error: unused variable 'ret' [-Werror=unused-variable]
 1569 |         int ret;
      |             ^~~
drivers/gpu/drm/nouveau/dispnv50/disp.c:1568:28: error: unused variable 'aux' [-Werror=unused-variable]
 1568 |         struct drm_dp_aux *aux = &nv_connector->aux;
      |                            ^~~

Move them into the same conditional block, along with the nv_connector variable
that becomes unused during that fix.
