Subject: [PATCH 28/42] PCI: aardvark: Free config space for emulated root bridge when unbinding driver to fix memory leak

From: Pali Rohár <[email-masked]>
Date: Thu, 6 May 2021 17:31:39 +0200

Do it after disabling and masking all interrupts, since aardvark interrupt
handler accesses config space of emulated root bridge.
