From b280a97d1caf6fe1d38b51ebb31219391f5ad1a0 Mon Sep 17 00:00:00 2001 From: Nick Pelly <npelly@google.com> Date: Fri, 15 Jul 2011 13:53:08 -0700 Subject: [PATCH] omap-serial: Allow IXON and IXOFF to be disabled. Fixes logic bug that software flow control cannot be disabled, because serial_omap_configure_xonxoff() is not called if both IXON and IXOFF bits are cleared.
