Subject: [PATCH] staging: media: atomisp: Use kvfree_sensitive in a few places
Date: Wed, 9 Sep 2020 20:53:50 +0100 [thread overview]
Message-ID: <20200909195403.225084-1-alex.dewar90@gmail.com> (raw)
In the file pci/sh_css_params.c, there are a number of places where
memset+kvfree is used, where kvfree_sensitive could be used instead. Fix
these occurrences.
Issue identified with Coccinelle.
