From 5288d522a9879a5ea71a8a1cd76df78f39e7a675 Mon Sep 17 00:00:00 2001 From: Russell King (Oracle) Date: Fri, 27 Jan 2023 10:40:14 +0000 Subject: nvmem: core: fix return value 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.
