It doesn't fix any functional problem. The point of this patch
is to increase the code readability by lifting some of the ambiguities
that appear when using an integer variable as boolean.

My understanding is that by explicitly using a boolean declaration
when it is relevant it clearly informs the reader that the variable
is going to represent a binary state. Moreover, using the keywords
true and false help indicate that the variable will not be involved
in any computation other than boolean arithmetic.

That being said, I am new to kernel contribution and I feel that
a more compelling case may be made here:
