[PATCH v3 12/12] crypto: LLVMLinux: Remove VLAIS usage from crypto/testmgr.c
From: <hidden>

Herbert Xu, "David S. Miller", Linus Torvalds
From: Jan-Simon Möller <redacted> Replaced the use of a Variable Length Array In Struct (VLAIS) with a C99 compliant equivalent. This patch allocates the appropriate amount of memory using a char array using the SHASH_DESC_ON_STACK macro. The new code can be compiled with both gcc and clang.
