[PATCH 5.10 139/139] nvmem: core: fix return value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Russell King (Oracle) <rmk+kernel@xxxxxxxxxxxxxxx>

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.

Fixes: 560181d3ace6 ("nvmem: core: fix cleanup after dev_set_name()")
