arm64: ptrace: fix compat reg getter/setter return values copy_{to,from}_user return the number of bytes remaining on failure, not an error code. This patch returns -EFAULT when the copy operation didn't complete, rather than expose the number of bytes not copied directly to userspace. Signed-off-by: Will Deacon <will.deacon@arm.com>
