If nouveau_get_backlight_name() fails then this should return -ENOMEM but currently it returns success.
Fixes: db1a0ae21461 ("drm/nouveau/bl: Assign different names to interfaces") Signed-off-by: Dan Carpenter dan.carpenter@oracle.com --- This is from static analysis. In the original commit db1a0ae21461 ("drm/nouveau/bl: Assign different names to interfaces") then returning zero seemed to be a very deliberate choice. I do think it was wrong though and -ENOMEM is the currect return.
