[PATCH 4.14 128/173] tty: fix termios input-speed encoding when using BOTHER

4.14-stable review patch. If anyone has any objections, please let me know. -- From: Johan Hovold [ Upstream commit 1cee38f0363a88db374e50b232ca17b9a4c12fa0 ] When the termios CIBAUD bits are left unset (i.e. B0), we use the same output and input speed and should leave CIBAUD
