Hi Michal,

For the new code I think expectation is clear that it should fully comply the
coding convention, but for the base code we are more flexible, since it is
shared I understand that the small fixes may cause more maintenance cost.

Please try to fix as much as possible, at least please fix the obviously wrong
ones and fix the ones like below with best effort.

Thanks,
ferruh
