Subject: rxrpc: Return negative error code to kernel service
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cf69207afa2a750ba78782bb4ff4d72c1efb8e6b;p=linux-beck.git

rxrpc: Return negative error code to kernel service

In rxrpc_kernel_recv_data(), when we return the error number incurred by a
failed call, we must negate it before returning it as it's stored as
positive (that's what we have to pass back to userspace).
