That's not good in terms of readability, index declaration should
remain at the top of the function, should be possible if using
IS_ENABLED() instead
I'm wondering how to declare a variable inside a code block such as if
(IS_ENABLED(CONFIG_PPC32)) at the top of the function and use the
variable in another if (IS_ENABLED(CONFIG_PPC32)). Is there any good idea?
You declare it outside the block as usual:
unsigned long some_var;
if (condition) {
some_var = something;
}
do_many_things();
do_other_things();
if (condition)
return some_var;
else
return 0;
