commit 0c4862b1c1465e473bc961a02765490578bf5c20 upstream.
Dan Carpenter points out that the return code was not set in commit 60c8b4aebd8e ("nvmem: core: fix cleanup after dev_set_name()"), but this is not the only issue - we also need to zero wp_gpio to prevent gpiod_put() being called on an error value.
