Replace 'devm_kmalloc_array(... | __GFP_ZERO)' with the equivalent and

It doesn't make much sense.
Actually devm_kcalloc returns devm_kmalloc_array(.., flag | __GFP_ZERO).
The only goal is to have a sightly less verbose code.
This saves one line of code and there is no need to wonder why we
explicitly pass __GFP_ZERO to kmalloc_array.
Mostly a matter of taste.
I prefer this part remain unchanged.

'devm_kcalloc' is inlined, so the binary should be exactly the same. >

'ctrl->genpool' can not be NULL, so axe a useless test in the remove
function.
