[PATCH 5.15 058/731] pstore/ram: Fix error return code in ramoops_probe()

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

 



From: Wang Yufen <wangyufen@xxxxxxxxxx>

[ Upstream commit e1fce564900f8734edf15b87f028c57e14f6e28d ]

In the if (dev_of_node(dev) && !pdata) path, the "err" may be assigned a
value of 0, so the error return code -EINVAL may be incorrectly set
to 0. To fix set valid return code before calling to goto.
