Subject: [PATCH AUTOSEL 6.2 02/17] platform/x86/intel: vsec: Fix a memory leak in intel_vsec_add_aux

From: Dongliang Mu <dzm91@...t.edu.cn>

[ Upstream commit da0ba0ccce54059d6c6b788a75099bfce95126da ]

The first error handling code in intel_vsec_add_aux misses the
deallocation of intel_vsec_dev->resource.

Fix this by adding kfree(intel_vsec_dev->resource) in the error handling
code.
