Subject: [PATCH 09/10] nvmem: core: fix return value
Date: Fri, 27 Jan 2023 10:40:14 +0000 [thread overview]
Message-ID: <20230127104015.23839-10-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20230127104015.23839-1-srinivas.kandagatla@linaro.org>
From: "Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>
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.
