[PATCH AUTOSEL 5.4 09/24] test_objagg: Fix potential memory leak in error handling

From: Sasha Levin <sashal@kernel.org>
Date: 2020-06-23 17:36:20
Also in: lkml, stable
Subsystem: library code, objagg, the rest · Maintainers: Andrew Morton, Jiri Pirko, Linus Torvalds

From: Aditya Pakki <redacted>

[ Upstream commit a6379f0ad6375a707e915518ecd5c2270afcd395 ]

In case of failure of check_expect_hints_stats(), the resources
allocated by objagg_hints_get should be freed. The patch fixes
this issue.
