[PATCH][next] atmel: Fix atmel_private_handler array size

From: Kees Cook
Date: Mon Oct 17 2022 - 22:38:10 EST


Fix the atmel_private_handler to correctly sized (1 element) again. (I
should have checked the data segment for differences.) This had no
behavioral impact (no private callbacks), but it made a very large
zero-filled array.
