From 08557db2c9fd5660ac788b6945affdf761ce2463 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 9 Apr 2021 14:08:17 +0300 Subject: [PATCH] HSI: core: fix resource leaks in hsi_add_client_from_dt() [ 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().
