Subject: [008/244] omap-serial: Allow IXON and IXOFF to be disabled.
3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: Nick Pelly <npelly@...gle.com>
commit b280a97d1caf6fe1d38b51ebb31219391f5ad1a0 upstream.
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.
