I agree that this is technically correct, but a lot of people don't
seem to know that so we get a lot of comments about this code for the
variables that are not explicitly set. Seems less confusing to
initialize them even if it not necessary. I don't have a particularly
strong opinion on it however.
Agree with Alex.
Especially for the module parameters we should have a explicit init value
for documentation purposes, even when it is 0.
Why is this one tiny driver somehow special compared to the entire rest
of the kernel? (hint, it isn't...)
And it certainly shouldn't :)
Please follow the normal coding style rules, there's no reason to ignore
them unless you like to constantly reject patches like this that get
sent to you.
Yeah, that's a rather good point.
Not a particular strong opinion on this either, but when something
global is set to 0 people usually do this to emphases that it is
important that it is zero.
