Cc: linux-sparse@vger.kernel.org MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Content-Disposition: inline X-Google-Sender-Auth: 8f676a686572f7bf Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Change prototypes for __chk_user_ptr and __chk_io_ptr to take const void* instead of void*, so that code can pass const void* to them. (Right now sparse does not warn about passing const void* to void* functions, but that is a separate bug that I believe Josh is working on, and once sparse does check this, the changed prototypes will be necessary.)
