From c1f2c81631df7654c249a457b7a54bbc36042248 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 22 Sep 2023 10:52:15 -0700 Subject: memory: atmel-ebi: Annotate struct atmel_ebi_dev with __counted_by Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct atmel_ebi_dev.
