Wouldn't it be simpler to make this take and return 'void *'? Then the callers
wouldn't need to cast to/from 'unsigned long'.
Also, aligning to a 1-byte boundary is a no-op.
So, please consider the following:
static inline void *aes_align_addr(void *addr)
{
if (crypto_tfm_ctx_alignment() >= AES_ALIGN)
return addr;
return PTR_ALIGN(addr, AES_ALIGN);
}
Also, aesni_rfc4106_gcm_ctx_get() and generic_gcmaes_ctx_get() should call this
too, rather than duplicating similar code.
