rs_startup() allocates a transmit ring buffer that is used to buffer reads and writes from/to serial data register. This buffer can be allocated with kmalloc() as there's nothing special about it to go directly to the page allocator. kmalloc() provides a better API that does not require ugly casts and kfree() does not need to know the size of the freed object. Replace use of get_zeroed_page() with kzalloc() and free_page() with kfree().
