Subject: [PATCH 2/3] atomisp: fix vfree of bogus data on unload
Date: Mon, 06 Nov 2017 23:36:45 +0000	[thread overview]
Message-ID: <151001140261.77201.8823780763771880199.stgit@alans-desktop> (raw)
In-Reply-To: <151001137594.77201.4306351721772580664.stgit@alans-desktop>

We load the firmware once, set pointers to it and then at some point release
it. We should not be doing a vfree() on the pointers into the firmware.
