[mythtv-users] LIRC kernel strangeness with more than four devices

	I had been playing around with four HDPVRs attached to single machine 
and all was well. Once I attached the fifth the kernel started 
complaining loudly and a sixth took the machine completely down.
	After I bit of tail chasing I tracked it down to 
lirc/drivers/lirc_dev/lirc_dev.h which sets

#define MAX_IRCTL_DEVICES 4

	Doing a bit of research it appears this is an arbitrary limit since it 
used to be 2 and it was simple to raise it to 4.

	I'm going to do a bit of recompiling later, but though I'd post in case 
other people are considering attaching several devices to their machines.
