If gf100_bar_new_() fails then "bar" is not initialized. Fixes: 5bf0257136a2 ("drm/nouveau/mmu/r535: initial support") Signed-off-by: Dan Carpenter <dan.carpen...@linaro.org> --- It looks like this was intended to handle a failure from the "rm" func but "rm" can't actually fail so it's easier to write the error handling for the code as-is.
