With gcc 4.0.2:
drivers/char/cyclades.c: In function 'cyy_interrupt':
drivers/char/cyclades.c:581: warning: 'info' may be used uninitialized in this function

:    cyclades: introduce cyy_readb/writeb

In fact the true branch which uses uninitialized 'info' can never
happen because chip is always less than ->nchips and channel is
always less than 4 which we alloc.

So behave similar to rx handling and remove the test completely.

I wonder why gcc 4.4.1 doesn't spit a word.
