Input: use resource_size when allocating resources
Use the function resource_size, which reduces the chance of introducing off-by-one errors in calculating the resource size. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct resource *res; @@ - (res->end - res->start) + 1 + resource_size(res) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
