[BUG ?] irda: via-ircc: condition with no effect

From: Nicholas Mc Guire <redacted>                                      

scanning for trivial bug-patters with coccinelle spatches returned:
./drivers/net/irda/via-ircc.c:598
	WARNING: condition with no effect (if branch == else)

This code was added prior to the transition to git (Linux-2.6.12-rc2) so
I was not really able to track back what the intent was.

drivers/net/irda/via-ircc.c - line numbers from 4.1-rc7
598                 if (IsSIROn(iobase)) {  //sir
599                         EnGPIOtoRX2(iobase, OFF);                          
600                         WriteGIO(iobase, OFF);
601                         EnRX2(iobase, OFF);     //sir to rx2
602                 } else {        // fir mir
603                         EnGPIOtoRX2(iobase, OFF);
604                         WriteGIO(iobase, OFF);
605                         EnRX2(iobase, OFF);     //fir to rx
606                 }

Given the comments that indicate that the if/else case actually are
different this may be a bug - if not the comments might need fixing.

thx!
