Hmm, another OMAP serial patch that wasn't Cc'd to linux-omap
where OMAP users might have seen it. :(
I just bisected a strange problem in linux-next on OMAP3 down to
this patch. Reverting it fixes the problem.
On OMAP3530 Beagle and Overo, after boot, doing a 'cat
/proc/cpuinfo' was not returning to a prompt, suggesting
something strange with the FIFO. Hitting return gets me back to
a prompt.
Greg, this one should also be dropped from tty-next until it can
be further investgated and the problem solved.
