Subject: [PATCH][next] drm/i915/selftests: fix memory leak of 'spin'
Date: Tue, 19 Feb 2019 15:01:29 +0000	[thread overview]
Message-ID: <20190219150129.12728-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

There is a memory leak of 'spin' on an error return path. Fix this by
kfree'ing spin before the return.

Fixes: c06ee6ff2cbc ("drm/i915/selftests: Context SSEU reconfiguration tests")
