SubjectRe: [PATCH] x86/sgx: Initialize "ret" in sgx_ioc_enclave_add_pages()

That length is:

* @length: length of the data (multiple of the page size)

I think we wanna fail this even earlier when it wants to add data of
length 0 because that sounds nonsensical to me. Or is there some use
case for zero-length data?

Btw, pls CC lkml on patch submissions.

Thx.
