[PATCH] rio: typo in bitwise AND expression.

[Willy Tarreau]

Hi Rogier,

here's a patch to fix a typo in rio_linux which affects both
kernel 2.4 and 2.6. It's not big deal it seems as it only
affects the irq-less path.

I found this one like that :

 $ grep -r '[^&]&[^&]*![^=]' drivers/char/

I'm sure others will find more efficient rules to catch such
errors.

Regards,
Willy
