dmaengine: st_fdma: Annotate struct st_fdma_desc with __counted_by 2023-09-28T11:12:14+00:00 Kees Cook keescook@chromium.org 2023-08-17T23:58:48+00:00 8279f0b476f37c51de2ed8bd70d770b2893dd2fa 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 st_fdma_desc.
