Subject[PATCH 5.10 341/530] HSI: core: fix resource leaks in hsi_add_client_from_dt()
Date
From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit 5c08b0f75575648032f309a6f58294453423ed93 ]

If some of the allocations fail between the dev_set_name() and the
device_register() then the name will not be freed. Fix this by
moving dev_set_name() directly in front of the call to device_register().

Fixes: a2aa24734d9d ("HSI: Add common DT binding for HSI client devices")
