Roman Kagan 666265036f chardev/char-socket: tcp_chr_sync_read: don't clobber errno ... After the return from tcp_chr_recv, tcp_chr_sync_read calls into a function which eventually makes a system call and may clobber errno. Make a copy of errno right after tcp_chr_recv and restore the errno on return from tcp_chr_sync_read.
