[Michael K. <mf...@us...>]

Update of /cvsroot/linux-vr/linux/include/asm-mips
In directory slayer.i.sourceforge.net:/tmp/cvs-serv17112/include/asm-mips

Modified Files:
	serial.h 
Log Message:
Fix the mutual exclusivity handling between the IrDA and RS-232 modes of
the shared VR41xx UART, and clean up a bit.

The locking seems to work now, but it's not properly setting the hardware
to IrDA mode for some reason.
