You've hit the rather subtle rules of select vs default. What happened is that SERIO is selected to m, but SERIO_I8042 isn't selected so the default of y is used instead. We already had the problem in the past that select and default don't work well together, so this patch cleans this up and makes the rule hopefully more straightforward. Basically now the value is calculated like this: (value && dependency) || select where the value is the user choice (if available and the symbol is visible) or default. In this case it means SERIO and SERIO_I8042 are both set to y due to their default and if SERIO didn't had the default, then the SERIO_I8042 value would be limited to m due to the dependency. I tested this patch with more 10000 random configs and above case is the only the difference that showed up, so I hope there is nothing that depended on the old more complex and subtle rules.
