linux-toradex.git/drivers/crypto/aspeed/aspeed-hace.h, branch v6.5-rc4 Linux kernel for Apalis and Colibri modules crypto: aspeed - Replace zero-length array with flexible-array member 2023-01-20T10:29:31+00:00 Gustavo A. R. Silva gustavoars@kernel.org 2023-01-10T01:39:17+00:00 f104b2169e6841b1629ff8cea15b751bc6f9a0e7 Zero-length arrays are deprecated[1] and we are moving towards adopting C99 flexible-array members instead. So, replace zero-length array declaration in struct aspeed_sham_ctx with flex-array member. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [2].
